Jeselnik is a class act. What's interesting to me is that the guy in the op, essentially has the same Roast style as Jeselnik. But the way they execute it is key.

I saw some of the ops bits from a comedy central roast, and they were really funny... But when you put him in the context of being at a trump rally wave saying stuff like this it's like "ohhh, you're not making subvertive jokes, you're just a bigot hiding behind 'comedy'"
