You know you've been in FIRST too long...

You first design your pumpkin (down to the mm) in inventor before even touching or carving it... oh, wait... that's what I spent my day doing....

You look forward to kickoff more then Christmas (or whatever you celebrate)

You have had plans to spray paint a giant FIRST logo on the floor of the quad... never gonna happen, anyway....

You design gearboxes, arms, and other strange FIRST related devices all over napkins at resturaunts, then attempt to explain the diagrams to confused waitpersons.
