any good comedies that don't seem to get enough praise? (filling my BB queue)

I thought Eulogy was really good and under-the-radar, but maybe I just missed it when it came out.

Romy and Michelle's High School Reunion. It's pure genius, and I have no idea why it never caught on.

Planes, Trains & Automobiles is my all-time favorite comedy. It's well-known, but never really was a bit "hit" (in the theaters or on home video).

Nurse Betty
Bulworth (makes a good rental since it is a weak release too.. non-anamorphic)
Still Crazy
Blast From the Past
Defending Your Life
The Out-of-Towners (original only)

Death to Smoochy and Scoop.

Slackers is a pretty bad movie but Jason Schwartzman comes pretty correct. Worth a rental.

Bowfinger
Unfaithfully Yours (Preston Sturges)

I think "Ali G Indahouse" is hilarious (and more fun than "Borat") but most reviewers disagree.

The con makes absolutely no sense whatsoever but I still found the 2004 version of The Big Bounce to be very funny. It is not strictly a comedy but I think Wasabi is pretty funny.

Also, I liked Bubble Boy (so ridiculous) and The Cable Guy (vastly underrated).

Another vote for Bowfinger... "Mother of God!"

Saving Silverman had it's moments.

Anything with Abbott and Costello is underrated.

MIDNIGHT RUN (Robert DeNiro and Charles Grodin)

Hmm, I think 10 ways to lose a guy and witherspoon's blonde films are last time I laughed at comedy. Actually I was thinking other day about this, since 80s, death of John Candy and such this genre has changed alot.

The Tall Guy
Tampopo
Love & Death
Modern Romance
The In-Laws (original)
Joe vs. the Volcano
God of Cookery

very dark:
Happiness
Little Murders

I can't understand the appeal to this movie. I loved the Jon Lovitz bit, but that was about it. Trying to turn child molestation and rape into a lighthearted idea, I don't know. It just wasn't for me.

Russians are Coming and Clifford. Yes, Clifford.

I agree with Midnight Run and Bowfinger.

Also:

Back to School (probably the best Rodney Dangerfield movie, aside from Caddyshack)
The Great Outdoors
Grosse Pointe Blank
The Road to Wellville (not the greatest movie, but definitely a different comedy than you're used to seeing)
Throw Momma From the Train

second that - and god help me, i thought Rocket Man was funny

Some recomendations from my collection:

Three O'Clock High.

Mitch Pilegi. Jeffrey Tambor. Casey (some jumble of letters).

These have been said already, but I agree with:

Midnight Run (it gets better everytime I see it).
Throw Momma From the Train (different, and better, than I thought it would be).
Bulworth (Watched it in my college philosophy class. I didn't really care for the ending though)


Not previously mentioned:

I love DtS. I never understood why it was panned.
