When Ishiro Honda directed the original Godzilla in 1954, it was his mission to present a terrifying monster who represented something topical, and he did so within the context of an almost completely humorless movie. Honda couldn't have imagined that, just ten years later, he would direct a movie in which his monster played boulder volleyball with a giant pterosaur and hurled swear words at a big caterpillar when she tried to break up their scuffle. Similarly, he probably didn't suspect that in 1965, Godzilla would celebrate victory against another monster by performing the 'Shie! dance. A happy moment for Godzilla; a bitter pill for Honda.

Though these silly moments weren't part of Godzilla's iconic first appearance, the goofier side of the King of the Monsters has become a beloved part of the franchise — and there are a lot of strange, silly moments in these films. Godzilla fans probably know about Godzilla's dance, the famous dropkick from Godzilla vs. Megalon, and the feature-length acid trip that is Yoshimitsu Banno's Godzilla vs. Hedorah.

However, there are many more WTF moments in the Godzilla franchise. Here are four of the most obscure and strangest parts of the series, complete with the fascinating backstories behind them.
