"Law and Order" Actress Sued -- **Doink Doink**

Ok, what's worse: An ungrateful actress or a talent agency that relies on oral promises? **Doink Doink**.

S. Epatha Merkerson got lots of jobs -- most notably a starring role as Lt. Anita Van Buren in "Law and Order" -- yet won't pay The Gersh Agency 10%. **Doink Doink".

In a lawsuit filed in L.A. Superior Court, the agency claims it had an oral deal -- as in trust me dahling, I'm good for it. **Doink Doink**.

The suit claims Merkerson pulled in $2,229,084 for "Law and Order alone." The agency wants at least $222,908.40.
