A mountain lion roaming the prairie found a bull, killed it and ate the entire bull. With a heavy belly, unable to walk, the lion laid in the tall grass moaning and roaring. Soon a hunter, attracted by the roaring, shot and killed the lion.
Moral: When you're full of bull, keep your mouth shut!
First sled I rode was a 71 Stinger II with a 400. 400's were around the fastest sleds you could get until 440's came out and those were the top of the line until the early '80's. Glitter red wedge shaped hood. Those Scorpions were the sharpest sleds built in the early '70s. All the other brands' had sleds that looked 10 years old even when they were new.
