At one of my customer sites, they like the heating turned up. It makes my laptop overheat, unless I prop up the end to let the air circulate around the vent underneath.
Sometimes I use my work diary to prop up the laptop, but this particular site doesn’t have enough room on the desk they provide.
But my “A” whistle is exactly the right size to fit under the end of the laptop.
Good job I keep my whistles in my laptop bag…
very handy. 
My high G whistle makes an excellent nasal catheter. 
Well, not exactly whistle, but I’ve used my blackwood-and-sterling Noy eight key timber flute as a back-scratcher. Publicly. I get these mildly horrified looks, and I’m, like, “What?”
Bosch had an interesting approach to alternative whistle uses.
I suspect Bosch of having had a profound distaste of whistlers, and that he envisioned a special place and just deserts in Hell for them.
I suspect Bosch of having had a profound taste for psychedelic substances.
Jeezdude,
ye make that sound like a baaad thing..
Slan,

If the head of your whistle is removable and you have some tape (electrical tape works well) you have an easily MacGuyvered’ blow-dart gun.
Purely unintentional.
