Dolly is the name of a sheep that has the honor of being the first mammal to be cloned by a group of scientists in England. Dolly was born July 5th, 1997 and she passed away in 2003. She lived for 6 and a half years, as a normal, active ewe.
Sheep from The Muppet Show. Sheep play cards (while Gonzo cheats) in Muppet Classic Theater. Lambs sing with Vanessa Williams on Sesame Street.

In nursery rhymes, they are said to follow their owners to school, and come home wagging their tails behind them.
