In class a few days ago:
My theory professor: *writing on the board* So, if you wanted to prove this, how would you do it?
Kid sitting a couple seats away from me: *starts to say something*
Professor: Whoa, whoa, whoa! You're using co-nondeterminism. That's like using an ICBM to kill a fly.
Kid: ...But it works, doesn't it?
Professor: Using an ICBM to kill a fly? Not particularly well.
That's when I snorted and nearly spilled my coffee. School is awesome.
