Party

I said that I thought someone had had a good idea and they said (pointing to head then groin);

'Up here for thinking and down here partying'

I cut them off and swapped them over. Bet that confused him.

Nose

Stating something was obvious, someone said;

'It's as plain as the nose on your face'

Not now I've sliced it off with a blunt razor.

Hatrack

I praised an employee for being clever and he said (pointing to his head);

'This isn't just a Hatrack you know'

I know. It also makes a great football.

Wash

I was explaining a problem I had and a friend said;

'It will all come out in the wash'

Blood doesn't and I'm covered in it after chopping him up into bite size chunks.
