Getting in heaven

Three men died on Christmas Eve and were met by Saint Peter at the
pearly gates.
"In honor of the season", Saint Peter said, " you must each possess
something that symbolizes Christmas to get into heaven on this holy
day."
The first man fumbled through his pockets and pulled out a lighter.
He flicked it on. "It represents a holy candle", he said.
"You may pass through the pearly gates", Saint Peter said.
The second man reached into his pocket and pulled out a set of keys.
He shook them and said, "They're bells"
Saint Peter said, "you may pass through the pearly gates.
The third man started searching desperately through his pockets and
finally pulled out a pair of women's panties.
"What do these symbolize?" Saint Peter asked.
The man replied, "They're Carols"
