Open Casket Birthday Prank

Pranks sometimes require a lot of planning. A few things need to happen and work out perfectly, which is why they call it a "practical" joke. In this case, people are at an open casket wake to say their final goodbyes to what they think is a deceased friend. When one particular couple walks up to the casket, the "deceased" pops his head up and says "Happy Birthday!" to the lady. She screams in horror, followed by a chorus of laughter from what we thought were a grieving bunch. The lengths people will go to for a good prank are astounding.
