IFC has given us a list of 10 comedies that were initially shunned but now have gained a cult following. I personally haven’t seen all of these movies, but from the ones I have [The Ten, Burn After Reading, Hot Rod], I wouldn’t mind taking another look at the other entries in this list.

Though I haven’t watched all the choices, I agree w/ “Hudson Hawk”, “The Jerk”, and “Johnny Dangerously”.
