You know you've been in the shop too long this weekend if:

[flcn43]

When the students are no longer allowed to talk to the programmer because he's got to finish up the autonomous mode

When you start replacing steel bolts with aluminum bolts just because you know in the end it will matter

When you realize that an all black background for your side panels will add weight because of the extra toner

When the large deadweight hammer becomes a viable programming tool

When you have recurring nightmares about your robot being destroyed in a scrimmage, days after it happened and was fixed

When you almost have an aneurism when the scale reads 290 and you don't realize there's an engineer crawling around on it

When you get teary-eyed about the time the robot is supposed to ship
