Not-So-FunnyKay Underwood, a 20-year-old girl from England, becomes temporarily paralyzed every time she has a fit of giggles. She suffers from cataplexy, a muscle weakness triggered by extreme emotions, which results in her collapsing when she laughs, although she can still retain her hearing during all instances of paralysis. (Another person with a similar condition collapses when he experiences "extreme smugness.") You'd expect that people would be understanding and sympathetic, right? One asshole woman hit her over the head after Underwood inconvenienced her by collapsing on some stairs and The Daily Mail takes pictures of her mid-giggle for their article (real nice, you guys!). Underwood says that she is currently on medication to help control her condition. [Daily Mail]
