Alan Alda lit up Twitter with a throwback video of himself tap-dancing with his granddaughter.

The "M*A*S*H" star posted the video over the weekend and it's tallied more 54,000 likes and 4,000 retweets.

The garage video is rough, and laughter is heard from onlookers.

Alda, 83, loves it, maybe because in all that shuffling, jumping and tapping is such a sweet moment between grandpa and granddaughter. As the SAG Life Achievement Award winner says in the caption: "I love this video. My granddaughter and I trying a way-under-rehearsed tap routine when she was about 9. One performance only in the garage."

Alda, who revealed last year he was diagnosed with Parkinson's, is clearly having a ball in the video.

It's not known which of his granddaughters is featured. The acting legend has eight grandchildren, and several of them attended the 25th SAG awards with Alda when he received his lifetime achievement award.
