Here's a cool video of a 75-year-old man doing some pretty bad ass yo-yo tricks in L.A. this weekend.
The 75-year-old man happens to be famous.
His name is Tom Smothers.
If you don't remember who Tom Smothers is, ask your grandpa. If your grandpa isn't around, watch the clip from his and his bro's famous variety show back in 1969.
