According to her twitter stream Alyson Hannigan will be on an upcoming episode of the Simpsons. Kinda of fun…she did told people as a guessing game. Read her tweets and see if you would have guessed the Simpsons:

I got to do something today that I have wanted to do for 21 years!!! Any guesses?

Okay hint #1: it involved work

Hint #2: didn’t have to go into make up/hair for the job

For part 2 of this… do you think she will play herself or will be TV related( HIMYM or Buffy)…or something COMPLETELY different!?
