jon gilliam is the modern rambo. Ryan is his sidekick. He runs around naked in football cleats with his big maltball nipples, screaming, "Get off my shit!" In his crappy apartments with his fat ass mom who's got a bearded clam when she walks, "Squishy, Squishy."

I think the new air con “manager” has been on a Jon-athon since he arrived… I have no idea what he does other than turn up late, leave early and shirk his responsibilities.
