Here's video of 26-year-old professional athlete Jeremy Lin in a foot race with a 55-year-old homeless guy in L.A.
So the question ... who ya got?
It all went down over the NBA All-Star break -- Lin and some of his pals decided they would help out in the community by socializing with some of the less fortunate and serving up food.
That's when one of the men decided he wanted to serve Jeremy -- and challenged the pro basketball player (who's 29 years his junior) to a foot race in the park.
Check out the video -- the man claimed he was "pretty quick for 55" and we gotta say, he moved pretty well against Lin.
BTW -- props to Lin, who's been going above and beyond the call of duty to help out the less fortunate ever since he moved to L.A. The guy's a philanthropic force to be reckoned with.
