What is the difference between comedy and satire? I think anything
that makes me laugh (esp with the George W. Bush administration vs.
Jon Stewart) is satire but that's not right, right?

I don't think all comedy is satire. As an example, I find many Monty
Python skits to be laugh-out-loud funny. The ones I like the best are
the skits filled with surreal and ridiculous things. The dead parrot
nailed to a perch in the pet store, for instance. Or the "crunchy
frog" chocolates. Or the exploding penguin. There isn't any satire in
those skits (not that I can see, anyway). But they tickle my funnybone
immensely.

satire = comedy but comedy =/ satire : 

Benny Hill is not being satirical. He's being funny (or supposed to be funny). 

Seinfeld (if to take a funnier example) as well.

Maybe this will help.  Here are two definitions of comedy and two of satire:

# light and humorous drama with a happy ending
# drollery: a comic incident or series of incidents

# Comedy is the use of humour in the performing arts. It also means a
performance that relies heavily on humor. The term originally comes
from theater, where it simply referred to a play with a happy ending,
in contrast to a tragedy. The humor, once an incidental device used to
entertain, is now an essential aspect of a comedy.

Satire:
# sarcasm: witty language used to convey insults or scorn; "he used
sarcasm to upset his opponent"; "irony is wasted on the stupid";
"Satire is a sort of glass, wherein beholders do generally discover
everybody's face but their own"--Jonathan Swift

# Satire is a literary technique of writing or art which principally
ridicules its subject (for example, individuals, organizations, or
states) often as an intended means of provoking or preventing change.
In Celtic societies, it was thought a bard's satire could have
physical effects, similar to a curse. A satirist is one who satirizes.
en.wikipedia.org/wiki/Satire

# 1. the use of ridicule or scorn, often in a humorous or witty way,
to expose vices and follies. 2. a literary example of such ridicule or
scorn.

I include a third definition of satire when I saw that is by Jonathan
Swift, one of the greatest English satarists.  His "Gulliver's
Travels" was a satire on situations in his day, and understood as
such, but some of the book is comical without knowing this.

You can find more definitions on Google be searching with
define:comedy   or   define:satire     (note:  colon without spaces).

My favorite quote about that is the legendary George S. Kaufman line,
"Satire is what closes on Saturday night."

Here's a link to a nice PBS 2001 "Great Performances" interview with
writer Larry (M*A*S*H*) Gelbart, who quotes Kaufman and talks about
comedy and satire.

Here's a good web site that sorts out the different types of comedy:

Here's an interesting quote by the wonderful writer, Dawn Powell:

"Satire is people as they are; romanticism, people as they would like
to be; realism, people as they seem with their insides left out."
