as a failed teacher (i sucked at it-- i mean really, really sucked) i envy JC Okie and the chilled cat
my only imaginary friend when i was a little kid was "my teacher"
When you say you sucked at it -- really, really sucked, I wonder how. Maybe your humor was just a little too "edgy" for the students? What grade did you teach? That makes a difference. I taught college freshmen and sophomores, and they "got" me.
