Found a few more that are alright...

Some jumper-cables and a bra walk into a bar...

The jumper-cables find a seat and the bra approaches the bar and asks for 2 beers.

The barman says "Sorry I can't serve you"
The bra says "Why?"
The barman says "Well you are clearly off your tits and your friend over there looks like he is gonna start something!"

lol...

A termite walks into a bar and asks "Where is the bar tender?"...
