The story I’ve put together, from the multiple found sauces: Sam Morrison bet his 53 year old dad Mitch that he couldn’t backflip. Sam mouthed-off, and Mitch bet his son that he couldn’t backflip every day of 2011. Sam won.

Sam’s a Syracuse student and his videos went viral among the students as the year went on, but it looks like after the 365th flip, the internet did its thing, and Sam (“the Cobra”) himself posted the compilation video on Reddit.

Check it out:

Sam told the NY Daily News that his dad has been getting calls non-stop congratulating him on his son’s success. “He said at one point he had to just put his phone down and smile to himself,” Sam said. “I teared up when I heard that. To me, that is more meaningful than 1 million views on YouTube.”
