In Family Guy, there is a recurrent meme of an ostrich who sarcastically laughs "ha hahhhh":
Is there an explanation or back story for this meme?
He first appears in the episode "Oceans Three and a Half" when Peter turns on Three and a Half Men, which begins with the line "Three and a Half Men was filmed in front of a live ostrich." After a lame joke, the ostrich is shown laughing as the lone audience member.
He appears in several later episodes, reprising his role as the ostrich laughing at a lame joke. In one episode he is identified as "Eddie" by other ostriches. That is the extent of his backstory.
