I told a good one today.

We're talking over some Greek myths...Prometheus, Pandora, that kind of thing.

STUDENT: Is it possible to have a gift from hell?
ME: I'm not sure. What are you thinking?
STUDENT: I think it'd be more like a curse or something.
ME: Yeah. Gift from hell feels like an oxymoron. What do you have in mind?
STUDENT: You know...something like a little piece of hell, all wrapped up in a pretty package.
ME: A little piece of hell wrapped up in a pretty package?
STUDENT: Yeah.
ME: Sounds like my ex-girlfriend.
