I think the "real" story was too boring so being the comic he is, embellished it a bit but we all get the story. Just way too much power for someone like him. However, he did talk about the time he took an MG or a Triumph and stuffed a V8 in it. Short skit:
He and his wife took the car to a nice restaurant and had it valet parked.
When he was done with the dinner and asked for his car, they gave him a few boxes of what was left of the British Car. The kid was unhurt but obviously, didn't keep his job.
