If he didn’t immediately head back out and continued to present a physical threat, he might just get himself shot - hard on or no.
I’d tell him to close the window and to not drip blood all over the carpet like last time. If I’m hungry, I’d ask him to bring me a peanut butter sammich and a glass of milk from the kitchen.
Throw a lamp or grab my guitar and crack him over the head with it.
Depends on who he is.
but no matter who he is, he has to lose the butcher knife.
Who said anything about teeth? :eek:
Oh no no no no…NOT the guitar.
Throw a lamp, throw a boot, hell throw your mother before you throw the guitar.
a) Have wild, passionate, hot, steamy, kinky sex.
b) (real answer) Scream, bang him over the head with the lamp (it’s old anyways), and run like crazy. Call the police from the next… eight frillion blocks over.
I’d try to remember my keys next time, and make a mental note that I can’t use a knife to open my locked front door.
Wait a minute-
Is it a butcher knife, or an odd knife with a lucite handle?
Is he completely naked or is he wearing a black taffeta mask, and has inflatable bat wings attached to his shoulders?
I always check those things to be sure it’s another guy coming in and not my reflection as I head out.
Time for a knife fight! Time for cock fight!
Using my GI Joe Kung Fu grip take his knife, cut off his penis with it, and begin training my new slave eunuch.
If he actually came through the window, I’d have to conceed that the geeks who think Superman could never have sex with a normal woman are right.
If it were my naked man with a hard-on and a butcher’s knife coming through the window, I’d just sort of wonder if he locked himself out. He’s a fabulous cook. 
Strange naked men will get shot. Dude, I’m armed.
That is exactly why I keep a loaded gun alongside my bed. Well, not exactly, but close enough.
Never go to a gun fight with only a knife and a hard on.
I’d pray I didn’t freeze up this time. If that plan worked - then scream and run.
Slam the window down on his boner?
“Oh, Dad. Let’s get you back to your room.”
I keep a baseball bat handy so I’d been trying to get a strike on two balls.
shakes fist Note to self: do not read funny SD threads while eating or drinking.
Sic my attack crocodile on him? (Okay, so it’s a stuffed one, but hey)
Applaud? (5th floor flat with screened window, thanks much)
Scream and peg alarm clock at him, knocking him off the window a la’ a certain coyote?
Since I live on the fortieth floor… :eek: :eek: :eek:
