"Symbolic of Christmas" joke

Three guys die on Christmas Eve and are met at the Pearly Gates by St. Peter. "In honor of the Season," St. Peter says, "each of you must possess something that symbolizes Christmas."
The first man fumbles through his pockets and pulls out two lighters. Holding them up proudly, he flicks them on.
"What do they symbolize?" asks St. Peter.
"They're candles!" replies the man.
"Ah, yes! You may pass through the Pearly Gates," says St. Peter.
The second man fumbles through his pockets and pulls out a couple sets of keys. He holds them up proudly and shakes them.
"What do they symbolize?" inquires St. Peter.
"They're bells!" the man replies.
"Ah, yes! You may pass through the Pearly Gates," says St. Peter.
The third man fumbles desperately through his pockets. Finally, he pulls out a skimpy pair of silk panties and proudly holds them up.
Puzzled, St. Peter asks, "What do they symbolize?"
"They're Carol's!"
