The Joie of Seating is an aluminum seat similar to the ones in the NASCAR series that was founded by Randy LaJoie. I don't know what it has to do with Buckshot Jones though, other than he running into a table and showing no signs of pain or agony.
Also, zaw24fan, the joke was that Randy LaJoie and Buckshot Jones had a very fierce rivalry in the late '90s when they were both BGN drivers. It all started when Randy LaJoie got into the back of Buckshot in a race at Tally in 1997, causing a huge wreck.
Here are some of the many clashes:
