Jimmy Kimmel Accepts Rob Ford's ALS Ice Bucket Challenge (VIDEO)

It's one thing to dump a bucket full of ice water over your head. It's quite another to take time out of a trip and fill your fishing waders with ice cubes.

That's how late-night host Jimmy Kimmel responded to an ALS Ice Bucket Challenge from Toronto Mayor Rob Ford and others.

In a video posted on YouTube Monday, Kimmel can be seen wearing waders with only underwear on underneath as two assistants fill it with bags of ice and then water it down with a garden hose.

Now THAT'S painful.

By contrast, Ford simply had his brother Doug and retired hockey player Tie Domi lift a bucket over his head and dump it. The mayor said he was nearly knocked out by the cold water.

And who did Kimmel challenge to take a cold shower after him? None other than Matt Damon, who is already facing a challenge from Ben Affleck.
