It's always good for a laugh when an on-air personality does something funky. In this case we had a TVG dude walk off the set after touting a heavy chalk who bit the dust.
This caused a lot of chatter on the chat boards, but there was an honest explanation. Tony, a producer/director at TVG let people know what happened on the paulickreport.com (although the simple explanation did not squelch the comments) : "It was a joke. Frank said before the race that when a horse like this loses he heads straight for the exit when he’s at the track. After the horses hit the wire I told him in his ear to walk off the set."
It was a good joke apparently, because it certainly caused a stir.
