Yes to both. Had alot of fun with my auto teacher- old German guy- Mr. Schalburg. Everytime he left the room, about six of us would pick up his prized VW Beetle, rotate it 180* and set it back down. We'd see him come back in, Pause briefly looking puzzled, sometimes shake his head, and get back to things. One day, he musta stepped out a dozen times, and I swear he musta thought he was losing it!
In fact, he already lost it. He used to tell us that he had a bush pilot buddy of his periodically fly him over his house to see if his wife was cheating!!!
And I'll never forget how he taught us how to hand-pack wheel bearings, he said "Ziss schtuff schticks to your hands like someting schticks to ze sheets!" LMAO!
