Homer: [reading screen] "To Start Press Any Key". Where's the ANY key?
I see Esk ["ESC"], Catarl ["CTRL"], and Pig-Up ["PGUP"]. There
doesn't seem to be any ANY key. Woo! All this computer hacking
is making me thirsty. I think I'll order a TAB. [presses TAB
key] Awp...no time for that now, the computer's starting.
[reading screen slowly] "Check core temperature, yes slash no."
[types] Yes.
"Core temperature normal." Hmph. Not too shabby.
"Vent radioactive gas." [types] NO.
"Venting prevents explosi-on." Heeheee...whoa, this is hard.
Where's my Tab? Okay, then, [types] YES, vent the stupid gas.
[Cut to a farmer tending his corn. The gas release blows away
part of the crop.]
Farmer: Oh, no! The corn. Paul Newman's gonna have my legs broke.
