Twist Endings and Children

Filmjabber has a cute list up of twist endings in movies. I admit I haven't seen most of these, but those I have seen (Pyscho!) certainly qualify. But the list seems to have been assembled by children maybe by oldsters who have lost their long-term memory. Where is Captain's Paradise, for example? Or Kind Hearts and Coronets? I should think you would want to count Some Like it Hot, also; and the (original?) Producers. Or maybe these are just "zinger" endings; maybe comedy is a different item.
