Two men were on a boat in the middle of a lake, talking to each other.

?: It's been, what, 15 years?

?: About that, yes.

?: 15 years is a long time to wait, you can't imagine how much I've suffered…

?: You… suffered?

?: And now… the perfect opportunity presents itself. At last… I shall have my revenge!

?: What!?

Suddenly, one of the men pulls out a gun and points it to the other.

?: …Merry Christmas.

He soon starts firing and then falls out of the boat and into the lake. Leaving the other man in a daze.
