Eddie, the Live Studio Ostrich is a talking ostrich. In "Ocean's Three and a Half", Two and a Half Men is filmed in front of him as the sole audience member. The same ostrich gets the last laugh at the end of the episode.
He appears in the audience in "Inside Family Guy".
When Peter's sperm donation offspring all share a laugh at the word "semen" in "A House Full of Peters", the ostrich joins in. A separate flock of ostriches, who identify the first as "Eddie", share a similar laugh at his expense for being over at the wrong house.
