Do I NEED to prime it?

I had an engine sitting in a car on the side of my house for about 3 years, dropped it in another car and fired it right up without priming the oil system and it was fine... It ran over 150,000 miles before I rebuilt it again to keep it fresh....

Or do what Steven said and disconnect the coil and crank it for 30 seconds or so to get the oil through the system...
