The Kids' Choice Awards air tonight, and you know what that means -- gallons and gallons of green slime.

Over the years, some of the biggest names in showbiz --including Hugh Jackman, Snoop Dogg and Mike Myers -- have been slimed.

In 2010, Katy Perry took a high-powered stream to the face, knocking her down to the stage. Last year, Johnny Depp turned the tables, sliming members of the audience. The audience got their revenge though, flinging leftover green goo at  Russell Brand and "Modern Family's" Rico Rodriguez.

Check out the best Kids' Choice star slimings, below:

This year's host, Will Smith, better watch out!

Nickolodeon's 25th Annual Kids' Choice Awards air tonight at 8pm/7pm Central.
