Lisa Simpson files for divorce.

Doh!
Despite having all the answers on The Simpsons, Yeardley Smith could only come up with one solution this time around.
The character actress and vocal talent behind the animated Lisa Simpson for the past two decades has filed for divorce from her husband of four years, Daniel Erickson.
Per the petition filed Wednesday in Los Angeles Superior Court, Smith cited the most-checked box ever—irreconcilable differences—as the reason for the split. Their date of separation is "under determination."
The duo have no children. Smith has requested she not be ordered to pay spousal support and is looking to have her legal name changed back to Yeardley Smith, because she has apparently been toting the "Erickson" around since tying the knot in 2002.
