A couple were driving to a church to get married. On the
way, they got into a car accident and died. When they arrive in heaven,
they see St. Peter at the gate. They ask him if he could arrange it so
they could marry in heaven.
St. Peter tells them that he'll do his best to work on it for them.

Three months pass by and the couple hear nothing.
They bump into St. Peter and ask him about the marriage.

He says, "I'm still working on it."
