MOTORCYCLE CRAZY

I had lunch with a couple of my daughters yesterday. On the way back home I was driving north up the freeway and noticed a guy on a motorcycle that was weaving in and out of traffic. He caught my eye because he was a bit eratic when he was weaving in and out. We reached a straight stretch and I saw him look back over his shoulder at a pickup truck, then he changed lanes to the far left lane. The truck changed to the same lane. I noticed that there was no one in front of the motorcycle. Then he made his move. He stood up on the pedals and lifted his right leg over the motorcycle and then stood on the pedal (or whatever). He then changed feet, so his right leg was on the pedal - his body still being on the left side of the motorcycle. He is still doing 65 mph down the freeway and his hands are still on the handlebars. Then he leans down a bit towards the front of the cycle and lifts his left leg perfectly perpendicular to the motorcycle. It is sticking straight out at a 90 degree angle. He drives like that for a few seconds (still at 65 mph), then he puts it back down, changes his feet again so his left foot is on the pedal, and then puts his right leg back over the motorcycle and then sits down. Then he immediately changes lanes across 3 more lanes of traffic and exits on the big interchange to another freeway going west. I was also taking that interchange, and was about 4 cars behind him, but by the time I got down off of the overpass onto the freeway,he was gone. He must have taken the first exit. I have no idea where the pickup truck went . I wondered if someone in the pickup truck was video-taping his motorcyle stunt for either YouTube or one of those stunt TV shows? It was a bit scary, but it was quite impressive!
