There is (or was) a cult for this little comedy, and one can see why; it has transgressive humor (when the "tush" scene isn't the worst part, it's REALLY not for everyone), some great lines ("He made a caca in the bed"), and a legendarily grim alternate ending. It's not a great film; it's too short to really milk its scenario, and Carl Reiner's direction lacks the punch to really make it a classic. But the performances are great: George Segal and Ruth Gordon make the most out of the material.

I don't think this is the funniest movie ever made like some people do -- this had a following long before every grade Z picture started claiming to be a cult movie -- but it's engagingly bizarre and often funny. A few moments are notably crude for a 1970 mainstream film, but disgustoid modern movies like _Scary Movie_ actually make this one look respectable
