Some of these are just great! I did forget one that happened recently:

We have a sort of creepy neighbor whom my husband and I both try to avoid. Well, the other day I came around the corner with Lefty, and there the guy was, bent beneath the hood of his car (practically inside of it). I thought I could get around him quietly, but Lefty was feeling friendly and went up to the car to see what the guy found so interesting. I said, "No, Lefty; come on!" and the guy turned around at this and found Lefty's face an inch from his. He bolts straight up and tries to step back, but his feet are wedged between the curb and his car, and he starts making these sweeping motions with his arms in an attempt to stay upright but ends up on his rear end. The whole thing seemed to happen in slow motion. He seemed a little angry so I apologized profusely, and my cheeks felt very hot. He finally says it's okay and I go on my way, but I was still red-faced when I got home and reported the incident to my husband!
