Ashrita Furman holds the world record as the fastest skipper, an honor he attained by skipping about 26 miles in just under six hours. He also holds the very unofficial world record of the only guy crazy enough to try to set a world skipping record while holding a tiger on a leash.
Needless to say, the beast did not enjoy having a man skipping alongside him and, at one point, seriously considered chasing the skipping Furman like it would a gazelle. But though the 4-year-old tiger, named Hernfa, did not exactly skip along, neither did he bite Furman's head off, so in that sense, Furman won.
You can read all about that adventure on Furman's blog.
