Why I don't want to be a defense attorney:

In a trial on distribution of cocaine, a prosecutor is questioning the defendant on the stand:

Q: You didn't see any actual drugs?

A: No, sir.

Q: Would you know what they looked like if you saw them?

A: Yes, it's advertised on TV, too, sometimes in the commercials

Q: You see drugs advertised on TV?

A:Yes, you know, on news or something like that.

Q: And that's the only time you've ever seen drugs?

A: Roughly, yes.

Q: Roughly?

A: Yes.

The prosecutor then went on to prove that the defendant had failed three drug tests during the course of his pre-trial release.
