John Oliver - honestly I just cannot watch his show. I've tried many times, but I cringe so hard I have to turn it off, even if I'm alone in the room.
Just the way he talks and tries so damn hard to be funny (when it's really not at all).. Ugh, just his style of talking is grinding my gears.
He does talk about important things though, so he's doing a good job at that, but I just cannot watch it.
