I have an english professor right now, it's not so much his name that is funny, but the way he looks. When he walked into the classroom on the first day I thought "WOW! Mr. Rogers (from Mr. Rogers Neighborhood) is my teacher!" Turns out at elast 6 other people in the class thought the same thing!
Also, had a teacher in high school (again, the english teacher) who's last name is Way. (My freshman year it was Covarubius (I know I spelled it wrong) We would just call him Mr. C.)
