Short, one joke videos developed for facebook audiences.

Each video would probably be less than 30 seconds, and be able to be viewed without sound to take advantage of the Facebook autoplay function.  They could be simple, animated shorts, like an animated comic strip, or set-up pranks, or just a different way to present memes.

An example:

A shot of a woman in the throes of childbirth at a hospital.  She’s screaming and the doctors are giving instructions, her frazzled husband holding her hand.  Just as the you hear the baby start crying dozens of people burst from carefully designed hiding spots, waving signs, and tossing streamers and confetti.
