Matthew Tkachuk pokes fun at dad's dab

Keith Tkachuk honored his 14-year-old daughter Taryn with a celebratory dab after scoring for the St. Louis Blues at the 2017 NHL Winter Classic Alumni Game on Saturday.
But son Matthew Tkachuk was also watching and the Calgary Flames forward made sure his dad's move did not go unnoticed.

Keith Tkachuk, who scored 538 NHL goals, including 208 in parts of nine seasons with the Blues, broke out the dab to acknowledge Taryn after breaking a 6-6 tie in the third period of their game against Chicago Blackhawks alumni.
Even after the move reached highlight reels around the hockey world, the elder Tkachuk admitted he wasn't exactly sure what he was doing.
"[Taryn] was watching, so I had to do a dab after I scored for her," Keith said. "I don't know what it is, but I had to do it because she told me."
