Flex those little gray cells and pen an amusing caption for our newest cartoon!
UPDATE: Matt Perry won March's contest with the following winning caption:
"This is the test lab, the flight simulator is next door."
It's time to take time to flex the little grey cells and try your hand at caption writing. Gaze at Daniel Guidera's cartoon for a bit and then let us know what's going on by submitting your entry in the "post comment" field below.
Deadline is March 31.
Good luck and happy captioning!
