There's nothing like a little fun in the pool.

Especially if you're C-list celebrities with no jobs... or at least ones that offer a heck of a lot of time off in between seasons.

On the left, The Hills' Spencer Pratt and Heidi Montag chicken-fight their way to $10,000 paydays from a certain celebrity photo agency.

On the right, Dancing with the Stars' Karina Smirnoff and Mario Lopez show they're still an item, frolicking in Miami and apparently indicating that they'd welcome the challenge of taking Spencer and Heidi down. Hard.

Who would win a chicken-fight between Speidi and Marina?
