"Three blondes died and are at the..." joke

Three blondes died and are at the pearly gates of heaven. St. Peter tells
them that they can enter the gates if they can answer one simple question.
St. Peter asks the first blonde, "What is Easter?"
The blonde replies, "Oh, that's easy! It's the holiday in November when
everyone gets together, eats turkey, and are thankful..."
"Wrong!," replies St. Peter, and proceeds to ask the second blonde the same
question, "What is Easter?"
The second blonde replies, "Easter is the holiday in December when we put
up a nice tree, exchange presents, and celebrate the birth of Jesus."
St. Peter looks at the second blonde, shakes his head in disgust, tells her
she's wrong, and then peers over his glasses at the third blonde and asks,
"What is Easter?"
The third blonde smiles confidently and looks St. Peter in the eyes, "I
know what Easter is."
"Oh?" says St. Peter, incredulously.
"Easter is the Christian holiday that coincides with the Jewish celebration
of Passover. Jesus and his disciples were eating at the last supper and
Jesus was later deceived and turned over to the Romans by one of his
disciples. The Romans took him to be crucified and he was stabbed in the
side, made to wear a crown of thorns, and was hung on a cross with nails
through his hands. He was buried in a nearby cave which was sealed off by
a large boulder."
St. Peter smiles broadly with delight.
The third blonde continues, "Every year the boulder is moved aside so that
Jesus can come out... and, if he sees his shadow, there will be six more
weeks of winter."
