I just jumped about two feet higher than when I viewed Monique's commercial [oh yes, , Monique!] For reasons that are not worth mentioning, I have the screen out of my office window right now. If I have the window open I leave the screen in the window sill and leaning up against the window on an angle [to keep the bugs out]. All of a sudden the screen was flying across the room, things were crashing down all around the window, and I see a huge bat making a U turn nearly right above me! That was interesting. I guess their sonar doesn't detect screens. I think I need to change my shorts again.
