2. Muhammad Ali [speaking in Zaire, Africa]: "There's no country as great as the smallest city in America. I mean [here in Zaire] you can't watch television. The water won't even run right. The toilets won't flush. The roads, the cars--there's nothing as great as America."

3. Sexually active bisexual: “I’ll never get AIDS. I’m a very intuitive person. I would sense it if someone had something as degenerative as the AIDS virus.”

4. Ed: My friend Dirk is a college freshman at a state university in upstate New York. He is blonde, loves surfing, and has a very laid-back personality.

5. Liz: I can't believe I got a B- on this marketing paper. My friend Jill turned in this same paper in a different marketing class last semester, and she got an A.
Bob: Don't you realize it's wrong to plagiarize someone else's work?
Liz: That's your opinion. What's wrong for one person isn't necessarily wrong for another, and I say there's nothing wrong with plagiarism--as long as you don't get caught.
