Funny thing is, on my computer, F5 rasies the contrast.
I'm immune.
Anyway, I told this guy that Alt-F4 makes your font cursive, and that I had just found out.
So:
Idiot 1: I know that trick.
Idiot 2: I'm not that stupid.
Me: What trick?
Idiot 2: It shuts down your computer or whatever.
Idiot 1: Why don't you do it first.
Me: Oh that only happens if you press F5
Idiot 1: No, its F4
Idiot 2: I'm pretty sure it is F4
Me: Trust, me, I know what I'm talking about.
Idiot 1: Look, I will show you.
Me: Okay
(about four second later Idiot 1 is gone)
Idiot 2: ... wow...
Me: I guess he pressed Alt F4
Idiot 2: He's an idiot.
Me: Yeah.
Idiot 2: So I guess F5 does change fonts then...
Me: Told you.
(five seconds later, Idiot 2 is gone.)
