Me, yesterday, to class: Tomorrow you will either have a quiz or shovel my driveway. Student: $20?? Me to student: No, you don't have to pay me that much. You can do it for free.
Are you one of those cool teachers where all the students laugh when you tell a joke? Or are you one of those a-hole or geeky teachers that just make everyones eyes roll whne you try to tell a good joke?
