It's a smaller-scale "Mad Mad Mad etc World" with some crafty veteran gagsters (Gilford, Berle, Buono, Brennan, Bishop et al) doing their shtick. Small improbabilities build and build until you end up with a string of boats with wildly-costumed characters sailing in an improbable location from an impossible caper. Total on-screen madness, yet it made sense at every small plot step along the way. Tightly-constructed and very much a late-60s comedy. It's one of those favorites you're slightly ashamed of.
