dude, the 1400’s are like, sooo yesterday…
You need to go to gym for carry one of these bagpipes. Pipers in middle-ages can use them as heavy-weapons in Crusades 
If ever a thread title belonged on a T-shirt…
Gosh… !
Whaaa… !
iirc Julian Goodacre often sports a t: ‘World Domination through bagpipes’
odds are he was talking about this one
He actually says “Dudelsack Pawa”, which might be cryptic on a T-shirt. But better than “Macht durch Dudelsack” or “Dudelsack mit uns”. 
That guy sways so much he gave me a case of the vertigo.
I dunno if I could play anything called a “tootle-bag”.
That guy is my new internet BFF… Only problem is he doesn’t know it yet!

…You ain’t seen nothing yet! 
Even though the “German medieval” bagpipes are far from “medieval” - in fact, they are a (pretty noisy) invention being made about 30yrs ago in Eastern Germany, optically inspired by some ancient pictures - what You saw is just a very weak picture of some of the stuff offered. Makers like Jens Guentzel e.g. offer bells designed like the medieval “morning-star”-weapons (are these W.o.m.D.?), and every maker is proud to make his pipes a lot louder than GHBs! Also, there’s an entire scene of bands like “In Extremo”, combining the style and sound of “Rammstein” with medieval(-inspired) melodies on bagpipes… This scene in Germany - and spreading all over Europe - is TRULY weird… 
Btw.: “Dudelsack” has nothing to do with “tootle-bag” - it’s just a German expression related to the Eastern-European “Dudy”-type bagpipes coming into fashion in Germany since late 17th century, which turned into the general German word for “bagpipe” within the march of times…
Oh, dear. And it seemed so right, English and German being related and all…
You mean it’s not the same as a Tüte-sack?? Well, no wonder I couldn’t get any sound from mine …
And you call yourself a linguini-ist. Tutendsack.
What the…? 
Bagpipe = Sackpfeife (literally). Tootlebag is a literal translation of Dudelsack. Has a pejorative sound to it.
Once again: “Dudel” in the German word “Dudelsack” comes from the slavic word for Bagpipe (“Duda”, “Dude”, “Dudy” a.s.o.). It came into Geman language about 17.century when Polish and Czech Bagpipes became popular in Europe. So, literally “Dudelsack” means “Bagpipe-bag” - which, of course, doesn’t really make sense - it’s just a mixture between ancient “Sackpfeife” and Eastern-European “Duda”. So, still no tooteling, sorry…
I carry my German dictionary in a Dudensack. It’s very handy.
But what is the etymology of the Slavic word duda, dude, dudy etc.? It seems onomatopoeic to me (pure speculation, of course). In which case, “tootlesack” could be a very good translation, based on the original etymology, rather than the current, denotative Slavic meaning.
The thing is … “oodle” words are very funny to a native English speaker: doodle, noodle, tootle, kaboodle; and related words like addle, rattle faddle, tattle. Onomatopoeically, they connote a kind of randomness and chaotic expression - which seems to fit the sound of the bagpipe! And “tootle” means to play notes on a wind instrument. So there is no way to prevent English speakers from thinking of “tootlesack” when they hear the name of this ridiculous instrument. 
If anything, a historically regular sound correspondence between German and English is D → Th: Dach/thatch, dick/thick, Dorf/thorpe, Dank/thank, du/thou, dünn/thin, etc. This is the High German consonant shift. So the best English equivalent might be “thudelbag” or “thudelsack”.
From the Oxford English Dictionary:
I must remember to use that second citation at my next session. 
More, from: Jan Karłowicz et al., Slownik języka polskiego [Dictionary of the Polish Language].
Dudlió (cf. Dudlaó). 1. Grać niewmiejętnie na dętym instrumencie. 2. Grać na fujarce. [1. Play a wind instrument badly. 2. Play the (fipple) flute.]
I like the first definition.
Apparently, the Polish stem word “dud-” behind duda / dudy / dudlió has the same connotation as English “toot”, at least in modern usage. So maybe dudel = tootle is not unreasonable.
But, in all fairness it seems it would all the same be a bit of a remove once it hit the German, e.g. the English word “bloke” coming, as it has been attested, from the Irish buachaill óg.
Are you suggesting that maybe a better rendering might be “dude sack”?
As in: “Hey there, sister, don’t mess with my dude sack!”
Maybe “bloke sack” would work, too.
Oh, fer eww.
