Open Water Hilarity -- Perfect Comedic Timing For Blue Whale

This gigantic blue whale just proved scientists don't know everything ... with some deep sea humor that left a zoologist speechless.

Mark Carwardine was trying to play up for the camera how hard his job is trying to spot the giant sea mammals out in their natural environment ... when he got a big blue photobomb.

Whoever said animals don't have a sense of humor hasn't seen this video.
