The sketch where an African warlord asks one of his mooks to Mercy Kill him so he doesn't have to surrender to the enemy. The mook repeatedly screws up; first he stabs the warlord, without killing him. Then instead of shooting him in the head, he shoots him in the knee. Then when he actually is about to shoot him in the head, he runs of out bullets. Then he resorts to just hitting him over the head with the pistol. Then the warlord finally just tells him to grab some more bullets, only for the mook to throw a pot at him. After some more convincing, he goes off to find more bullets....
That would be Torque [Construction Noise] Lewith, from Nevada State Penitentiary. The middle part is pronounced by the sounds of a jackhammer.
The entire skit with the inner city substitute teacher who keeps mispronouncing his students' names, such as calling Jacqueline Jay-qwel-lin and Blake Ba-la-key, only to think they're messing with him when they try to correct him. With each polite correction he just gets angrier and angrier culminating in...
Teacher: Why didn't you answer the first time I said A-A-Ron.
Aaron: ... Because it's pronounced Aaron.
Teacher: SON OF A BITCH! (turns and around and swipes everything off his desk) YOU DONE MESSED UP A-A-RON! Now take your ass on down to O-Shag-Henessy's office right now and tell him what you did!
Aaron: Principal O'Shaughnessy?
Teacher:Get out of my goddamned classroom before I break my foot off in your ass! Insubordinate and churlish!
And then the punchline where the only kid he got the name right (Timothy, said as Tim-oh-thay) is a black kid that was out of view until the last second.
