When people fall. Babies, old people, anyone. It really is a bad habit but for some reason I really can't keep from laughing
I once laughed uncontrollably at an old man tripping and falling into a clothing rack at the store where I was working. That's when I knew I had a problem
I remember when I was in public HS some special ed girl ran up to a cholo and started screaming in his face and he was pushing her away and then she tried swinging on him and he launched her across the cafeteria floor ?
