Alf!
The brown creature from the popular 80's sitcom of the same name. A certain Law & Order actor bears a striking resemblance to Alf.
You might be stuck in the 80's if you still have an Alf T-shirt.

If you're 93 years old, you should know who Alf is. Actually, you should know who Alf is if you at least lived in the 80's. Even the 90's.

For those that don't know about Alf, his real name is Gordon Shumway. He is given the nickname Alf, which is an acronym of Alien Life Form. He hails from the planet Melmac. He is covered with an orange fur, and he looks like the cross between a mammoth and an orangutan. His favorite food is cats. Now you should have an idea on who Alf is.

Danny: "I'm watching the first season of Alf on DVD."
"Alf."
"ALF."
"You're 93 years old and you don't know what Alf is? Piece of crap!"
