I had one AG teacher in High school that had his bus licence and when ever he didn't feel like teaching he would say "I've got ol' #52 out back, let's go to the Jolly Cone" Ol' #52 was the worst POS the the motor pool had and the only bus that they would let Mr. Sylvia drive. He would just kinda slow down for the R/R crossings and open the door "good enough" and on more than one occasion he would be next to some guy at a light, open the door, look over the top of his "Cool Hand Luke, man with no eyes, sun glasses" then rev the engine. When the light changed he would take off as quick as the wore out old 352 would go, throwing kids out of their seats in laughter. One time he got it stuck in the mud out at the school farm and made all the boys push, when it got going he hit the gas spraying everyone with mud. Good times! 
Yeah, I've been in a bus like that.
