We've had limericks dirty and filthy, and we've had warped nursery rhymes. Can I put in a plea for something the same ... but different?

My wife works with adults with learning difficulties, and she's looking for shortish, probably funny poems, that conjure up a memorable picture - many of the clients don't write, but they can draw, and it'd be rewarding to see what they come up with. The poems can be cheeky, but basically clean - even though they're adults, tyou never know who you're going to offend.

Ones by Kenn Nesbitt have been going down well. Anyone got any others?
