Aaron's bird, Golden-cheeked Warbler (Dendroica chrysoparia), is an endangered species found in Texas, Mexico and Central America.

This episode received a 2005 Emmy nomination - Outstanding Art Direction For A Multi-Camera Series.

Originally, Perry turned down the role because of scheduling conflicts. It wasn't until he actually got the script and read what his part would be that he changed his plans to come.

The bird is nothing more than a puppet designed to fall by a tug of a string. The footage of the bird moving is edited in.

Rosario: Whenever I get together with my friends and talk about who works for the craziest bitch, I always win.

Will: That was some kiss, I emptied the dishwasher during it.
Grace: Oh my God! What is wrong with me? Why do I always do that?
Will: What, act like a giant whore?
Grace: We haven't even gone on a date and already I'm kissing him like he just got back from Iraq. Ohhhhhh, I always do this, I move too fast. Sexually, emotionally, everything.
Will: Well if you really like this guy, why don't you try slowing down. Get to know him, for once, don't think with your penis.

So Grace walked around New York with only one shoe on in the middle of winter? In a dress no less. Either Grace has gotten slightly dumber, or the writers forgot it was winter.
