Okay, this is probably a very old joke, but I haven't seen it yet, and that's what matters... Honest.
I thought it up the other day, then William Shatner hosted 'Have I Got News For You' last night and I've finished my exams with no better ideas to draw and post... Basically a concatenation of coincidence and sloth brings you this comic.
PS - I've never actually seen the original Star Trek...
Edit: Redrawn so it makes slightly more sense...
Glad it's clear now. Cheers again for pointing it out.
Cheers for the heads up; no point telling a joke nobody can understand...
