Not an instrumental embarassment but a singing one. I was singing 'Trouble In Our Fields' on Wednesday and got to the second verse when the shitzu ('what's a shitzu?' - one with no animals ho ho) in the pub suddenly came rushing up - tail wagging and very excited - and sat down in front of me and the started singing along with me.

It's very off putting but everyone was in fits of laughter. I did Hound Dog afterwards but he didn't like that.
