There is an online comic (not currently being updated frequently), but I still found it amusing to read at times:
http://thespiphobia.comicgenesis.com/ (It's a comic written about theatre from someone who is involved with the tech direction side of things).
One section from the "Lingo" link I really liked:
In is down, down is front,
out is up, up is back,
off is out, on is in,
left is right, right is left,
a drop shouldn't, a prop doesn't,
a purchase line will buy you nothing,
a block and tackle does neither,
the Green Room isn't (Thank God),
strike is work, and a run crew rarely gets anywhere.
Break a leg. (but not really).
Shut up still means shut up.
I got most of this (although I'm not sure what a purchase line is, nor a tackle, in relative terms of theatre), but it's still fun.
