What's your favourite?
This one came from a 10 year old:
Three guys were off to a Christmas party. The rule was you were only allowed in if you brought something Christmassy with you.
1st guy hands a bit of holly to the doorman - 'Yep, that's fine, in you come.'
2nd guy hands over a piece of mistletoe - 'Yep, that's fine, in you come.'
3rd guy has brought a pair of knickers with him. Doorman - confused - 'You can't come in with those - what's Christmassy about that?!'
Guy replies...
'They're Carol's'
