Wait, Did The Clippers Pretend To Stab Paul Pierce A Bunch Of Times?

The Clippers played in Boston last night, possibly marking former Celtics great Paul Pierce’s last chance to play in front of his old fans. Pierce received a warm welcome from the crowed when he was introduced, and then participated in a very strange skit with his teammates.

Is that supposed to be some kind of homage to the time Pierce was stabbed 11 times in a Boston nightclub? The Clippers are weird.
