It's also exactly what the people filming were expecting.

I was expecting him to trip or get cause by the current, falling off the stairs or into a manhole or whatever that was all of a sudden caught me by surprise.

I'm guessing manhole or storm drain, what with the flooding and all it probably dislodged itself.

Something similar happened to my friend's sister when we were eight years old. It was just as funny then as it is now.

Based on their costumes, this is a deleted scene from The Avengers starring Hawkeye and Black Widow, isn't it?

This isn't backfiring, this is one of those Cary Grant goofy but smooth ultrapussy acquisitions.

I was actually expecting a car to speed by and soak them with a rooster tail of water.

I also was expecting them to fall. Just not into a hole, let alone one that deep.

Nothing that dude was going to do was going to make either of them any less soaking wet. If anything he was slowing both of them down.

"There is something to be learned from a rainstorm. When meeting with a sudden shower, you try not to get wet and run quickly along the road. But doing such things as passing under the eaves of houses, you still get wet. When you are resolved from the beginning, you will not be perplexed, though you still get the same soaking." - 山本 常朝, Hagakure

Wang Chi: A brave man likes the feel of nature on his face, Jack.

Egg Shen: Yeah, and a wise man has enough sense to get in out of the rain!
