Kenny vs Spenny
It's my all time favourite show. If you haven't seen it, it might be your newfound addiction if you're the type into obscene, crude comedy.
Kenny is the epitome of an ENTP. Lack of tact, debate for the sake of pissing Spenny off, apathy for personal style/impressions, Ne dom...
His douchery is just highly amplified in this show, more so I should say NeTi unleashed.
Spenny is likely an ISFJ. They are the absolute antithesis of each other...
which they themselves see why their individual personalities bring drama, without having to write anything for the show. Some people think the show is scripted for being so extreme but I don't think it is. Spenny now has his own show series and he is... legitimately an awful actor.

Without watching the show, here is an old interview after the first/second season which can give you a glimpse of what it is.

At 02:30, George claims it's awesome Kenny was able to convince Spenny his mom died and in a short instance, Spenny's brief comment suggested "how is that funny?". He is for real. He's a virtuous, delicate man with a disturbingly high tolerance for Kenny's unfairness.
