Foster's 

Short for Foster's Home for Imaginary friends. When kids get too old they don't need imaginary friends anymore so they stay at Foster's until they get adopted by another child (presumably with no imagination of their own).
Foster herself is a little old lady who still has her imaginary bunny friend.

Mr. Unicorn, we regret to inform you little Stacy is dead, so you'll be staying at Foster's from now on.

Foster's Law 

The rule that "if I’ve Heard of Yer Da I Don’t Need To Hear From You", coined by Dawn Foster. Describes mediocre people who have jobs in the media not because of any talent of their own but because they have rich and famous parents, private schooling and family connections.

Giles Coren a prime example of how Foster's Law holds for almost every man bar Jesus.

Foster's Home for Imaginary Friends 

A cartoon created by the guy who did Power Puff Girls. It is about a 8-year-old named Mac who is forced to give up his imginary friend named Bloo. There are other characters including Eduardo, a mexican imginary friend; Terrance, Mac's bro; Wilt, a red imaginary friend; Frankie, a 22-year-old; Madam Foster, a old lady who runs the house; Herriman, a rabbit; Duchess, a fugly slut; and Coco, an insane thing.

The plots are interesting and creative, the characters are likable. A lot of the jokes use adult/crude humor, thus making the show not for children. Oh, and it's very funny!

Foster's Home for Imaginary Friends is very funny!

Foster's Home for Imaginary Friends 

A truly wonderful and imaginative show, one of the best originals Cartoon Network ever had. Beautiful animation and music, wacky characters and themes, a great sense of comedy and a big heart. Unusually complex characters, long ongoing arcs and young adult-oriented reference-laden humour makes for a viewing experience that is both highly comical and intelligent. Watching the hour long pilot is recommended for understanding the basic plot, although every episode is a laught riot you shouldn't miss.

"Did you watch Foster's Home for Imaginary Friends? Doesn't it have wonderful characters and an animation to die for? I whistle the theme song often, it's catchy."
