The car in the other lane next to me pulled a Gandalf for about 2 miles. He made sure I wouldn't be able to pass.
Bob: Damn, that girl at the end of the bar is looking fine, I think I'm going to try and make a pass at her.
Charles: No way man, she pulled a Gandalf already on 3 other guys who tried me make a pass at her tonight.
Question: Why didn't the chicken cross the road?
"Did you not have sex with her yesterday?"
"No, she Pulled-a-Gandalf"
