Helpful Brother
Brothers grow up together and go through life with an inseparable bond. If not in the literal sense, they are always there for each other when a hand is needed. Including when it comes to picking up girls.
This is a classic example of how brothers use each other as scapegoats when caught in an embarrassing situation. After being completely shot down, this guy claims he meant to be looking for a girl for his brother. Unlikely to be true, at least he looks like a good brother.
