Door Holding Disaster

Listen up, genius. The joke is that the dude's girlfriend is mad because he held the door open for another girl, thinking he's cheating. But, surprise, the girl he helped was in a wheelchair. It's funny because the girlfriend's jealousy is totally misplaced and makes her look dumb, just like you when you try to parallel park. Plus, it's a bit of a dig at how people jump to conclusions. And you, my friend, are the king of jumping to conclusions.
