Counting Sheep

Counting Sheep
Counting Sheep is a Flash screamer. This game invites the player to count cartoon sheep jumping over a fence while SEGA music plays and warning them not to fall asleep. However, after five sheep jump, a flurry of pictures of injured sheep and sheep carcasses appear very fast over a roar before cutting to the credits frame, which has some text saying "LOSER.", "omg you suck", as well as a Play again button.
