Oh man. I remember one time on US-63N in Arkansas there was an 18wheeler, a panel van, and me.
The truck was going faster than the van and wanted to pass, but the van would never get out of the left lane. So the dude kept trying to pass in the right lane, but kept running into traffic, and would have to slow down. I didn't have my CB at the time, but I was watching and knew he would be getting pissed. So eventually I got beside the truck and motioned that I would get him around the van. He let me ahead of him, and then I got in front of the van. Literally in the left lane just like the van, then started to slow down while the truck went past us. Once the truck was clear, the van went into the right lane to get around me. I proceeded to speed up to my cruise control (75mph) and passed the truck back. He was smiling big as hell and laughing as I went passed.
