OK. Video One - I chuckled inside for a second when she shucked and jived to the mic in the church. It sounded kind of like I was clearing my throat, but it was a form of laughter.
The other two.... ehh. I would lie to you but I don't think you want me to do that. I got nothing from those even close to humor. There's just something about her comedy.... I can't put my finger on the word. Maybe "obvious"? I don't know. I'm also not a big fan of the type of stuff like the end of that 3rd video, when the fat lady has peanuts go up her ass and "George Washington Carver" sticks his finger in it, licks it and discovers peanut butter. Not only is that not funny to me, it's crass and disgusting. Just cheap/obvious/easy humor, imho. Personally I think YOU are much funnier than anything I've ever seen from Sarah Silverman.
I'm sorry toots. You know I love you, but on this we are at an impasse it seems.
