Has anyone ever seen this tutor for the “Bleistift-Flöte” And I thought nowadays whistles are lead-free
Sehr nett, aber können Sie mit es auch schreiben? 
Blech!
(You can interpret that either way.)
This calls for retaliation:
what about calling the re¢ø®∆ærs “cube flutes” or “constrict flute”.
Ok, I know, it’s not nice to moeck bloeck-floetes…
Over here, the most common names for r..s (Blockflöte) are:
“Blödflocke” (“stupid flake”), “Sabberholz” (“droolwood”) and “Wimmerknochen” (“wow bone”)
Hits the nail on the head
