What Happens: Finding himself inconveniently located at a nuclear testing site moments before a live nuclear test, Indy hides himself in the fridge of a mocked-up home to avoid the effects of the blast.

Why It's Stupid: Well... because the fridge would be obliterated by the blast, and should it somehow be launched several miles through the air as in the film, Indy would be a broken, leaking sack of bones upon landing.

So crass and idiotic it’s joined ‘jumping the shark’ as shorthand for drastic loss of quality.
