Couple in Pennsylvania pranks mailman with extra-long envelope

— -- Billy Kelly, a comedian who lives in Lewisburg, Pennsylvania, decided to team up with his wife for an April Fool's Day prank on their mailman.

But this was no typical envelope.

The Kellys waited in their car for the mailman to arrive after they placed the long envelope in the mail slot of their door.
