Leave it to a teenage boy to attempt a prank during one of their parent’s important life moments.

As Rep. Roger Marshall (R – KS) and his family gathered around Speaker Paul Ryan, Marshall’s son raised his arm to his face to do a popular dance move called “dabbing” during the photo.

A confused Ryan asks if he is sneezing and when the teen says no, Ryan seems to realize what he’s doing and guides his arm down. However, the Speaker still needs to go home and look up dabbing it seems.

Just finished swearing-in photos. Nearly 300 members. Countless cute kids. Still don't get what dabbing is, though. pic.twitter.com/E2hFgyPYZT

And as is right, when such shenanigans go on, there are consequences.

Just so you know @SpeakerRyan: He's grounded. https://t.co/PGGhYXEfQv
