Yea I noticed that too,
The Officials doing the talking have serious and somber faces,
and the clown doing the sign language is acting like he's doing stand-up at a comedy club.
It reminded me of an episode of "Spin City" with Michael J Fox where he hired a "Signer" who didn't know signing and was riffing during a press conference and MJF ran out and tackled him on set. It was a funny bit.
