The other day, a friend of mine was being annoying to girls in the class. He would chase them, pull their hair, etc... Now I, as a total gentleman, pulled him aside and had a talk with him. He would not listen, so a big fight went down. We both threw some punches but he quite clearly lost. All the girls saw this happen and saw me as a metaphorical "knight in shining armour".
Long story short, I went through about 3 girlfriends since that. Guess that was a happy ending for me!
