I thought of another one!
How about "Appeal to the Majority"
I remember my mother used to say, "If everybody else jumped off a cliff, would you jump too?"
As a general rule, the Majority is always wrong.
George Carlin did the mathematical work to back this up:
“Think of how stupid the average person is, and realize half of them are stupider than that.”
Yes, this is one of logical fallacies. They call it "appeal to the people" or "appeal to the bandwagon" :-)
