Three guy's die on christmas eve. St Peter state's 'before entry to heaven can be granted you need to show me something that is symbolic of christmas'.

first guy offers a lighter, 'this St Peter represents a candle'
entry into heaven granted.

Second guy offers some key's and begins too jingle them, 'these St Peter represent the bells'
entry into heaven was granted.

Third guy offers a pair of thongs, confused St Peter looks @ him and say's 'are you crazy, how can thongs represent christmas'? third guy say's they''re carols...
