It's a really hot day, and a penguin takes his car to a mechanic. The penguin asks, "How long will it be?" The mechanic says, "Just a few minutes." So the penguin decides to go get an ice cream at the grocery store across the street. When the penguin gets there, he climbs inside the big freezer to sit and eat his ice cream. An hour goes by when the penguin looks at his watch, jumps out of the freezer and races back to the mechanic.
With ice cream all over his face and his stomach, he asks, "So how's my car?" The mechanic comes walking out wiping his hands on a rag and says, "Looks like you blew a seal." The penguin says, "No, I was just eating ice cream."
A mechanic was removing a cylinder head from the engine of a Range Rover when he spotted a well-known heart surgeon in the shop. The surgeon was there waiting for the service manager to come take a look at his Mercedes when the mechanic shouted across the garage: "Hey doc, can I ask you a question?"
The surgeon, a bit surprised, walked over to where the mechanic was working on the Range Rover. The mechanic straightened up, wiped his hands on a rag and asked: "So Doc, look at this engine. I open its heart, take the valves out, repair any damage, and then put them back in, and when I finish, it works just like new. So how come I get such a small salary and you get the really big money, when you and I are doing basically the same work?"
The surgeon paused, smiled and leaned over and whispered to the mechanic: "Try doing it with the engine running."
