Rick, you've forgotten you have an international audience (some of whom are too young to worry about incontinence)...
'Depends' - don't have them in the UK - I guess a rolled up copy of the Times will have to suffice!
'Wal-Mart' - don't have them in the UK either - ASDA is their equivalent here [I'll let you know which name I find quite ridiculous - Associated Dairies vs Wally Market...]
'Da' - obviously this word has no meaning in real English so the whole joke would fall completely flat if told to a British Bobby on a red London bus in Trafalgar Square.
Sorry to piss on your bonfire old chap!
