Stan's investment in cow futures with Calvin (and losing much money in the process) foreshadow his future gambling problems.
Early in the episode in the OCB conference room, Agent Anderson makes a masturbation motion with his hand as he says "bull...semen". Clearly this got past the censors assuming it wasn't noticed to begin with.
There are no deaths in this episode.
Anderson saying, "It would be wrong, but I could..." is a satire of Richard Nixon's famous admission on the White House tapes.
