Man goes into a pub with a piece of black tarmac under one arm and a piece of green tarmac under the other.
"Two pints of lager, please." "Why two pints?", asks the barman. "One for me and one for the road." "What about the other bit of road", asks the barman. "Oh no, you don't want to serve him, he's a psyclepath."
....with a lollipop under one arm and a purple sweet under the other.
"Two pints of lager, please." "Why two pints?", asks the barman. "One for me and one for the lolly." "What about the other sweet", asks the barman. "Oh no, you don't want to serve him, he's flippin' menthol."
