Look at this dude. If you walk into a lecture hall and see a guy who looks like he's still on an acid trip from Summer Jam at Watkins Glen in 1973, then it's going to be a good semester. This category of educator is most likely to prefer "intellectual exploration" to grades and will cancel at least a half dozen lectures on account of misplacing their car keys. Not all classes will be this easy, so enjoy.
