Sarah Silverman, available

If you like 'em smart, sarcastic and zaftig -- and let's face it, who doesn't? -- she's on the market again:

Late night host Jimmy Kimmel and comic Sarah Silverman have called it quits after five years of dating, reps for the couple confirm to Usmagazine.com.
The break up was mutual, a source says.
"Jimmy and Sarah will have no further comment," their reps Lewis Kay and Amy Zvi tell Us in a statement.

No comment so far from Matt Damon.

UPDATE: Also no comment from Ben Affleck.
