Sonya Thomas - Women's Nathan's Hot Dog Eating Contest - 40 hot dogs (with buns) in 10 minutes (7/4/11) [second place was far off the pace - only 28 dogs and buns]
Inspired by that impressive feat (and my own, in comparison paltry, but trying to set an individual record, eating) I decided to look into other world class eaters ....
