It isn't one of these innuendos is it?

Someone told me today that they reckon I didn't actually nut my bedpost but got caught up in the moment of one of my crazy trumpet solos and hit myself in the face with the bell-end (of the Trumpet).

You can hours of fun with Trumpet Innuendos...I did a whole 15 minute English presentation on them for my English Speaking and Listening thingy for GCSE last year.
