Ah yes, the Ocarina.

Had a mate who would play one, & I would refer to it as giving a tortoise a...well, you know what...

Thing is, I got in the habit of saying it to OTHER people, before ever saying it to him.

One time I said it he actually overheard me....while he was playing.

Honestly, the BEST noise you can get out of an Ocarina is the one where someone SNORTS with laughter while playing it....

This same guy also played the spoons, & one time at a Festival, he must have left them in his tent, & he acqured couple of plastic ones from somewhere, & rattled away happily enough, until I referred to them as TRAINING spoons, before he was allowed to progress to real metal ones...
