British:
To wake you up tomorrow. It goes back to the days in before alarms where they used to come around and knock on your door to wake you up. Moden UK or british type hotel clerks will still use the saying.
I'll knock you up in morning, we'll suck a quick fag and be off.

Bender: So it's settled! Elzar will teach me to cook.
Elzar: Absolutely not.
Bender: Aw, come on, I watch your show. You owe me!
Elzar: I owe you nothing. For starters your antenna's in my crotch, also I hate you, and finally, you can't cook for squat.
Bender: (he cries) What was the first one again?
Elzar: I hate you.
Bender: I thought that was the number two.
Elzar: I knocked it up a notch! BAM!!
