I liked The Born Dissenter on the Chappelle Show:
2005, New York - "Bloomberg's f**kin' up!!!"
1974, New York - "Carter's f**kin' up!!!"
1945, A-bomb - "Truman's f**kin' up!!!"
1863, on the Plantation - "Lincoln's f**kin' up!!!" "White folks are f**k' up!!!" "Quiet, here comes one now."
1697, Africa - "The Chief's f**kin' up!!! Here comes a boat with some white folks on it. Think I'll go check it out."
6 weeks later on the boat - "I f**ked up!!!"
Oops, make that:
1979, New York - "Carter's f**kin' up!!!"
