Pretty good
I liked how some of your jokes are really random. I really liked the cop integration, "Now I'm going to take off my sunglasses" Really funny! But I think some of your other jokes need more work as far as your timing goes. Like the Cowboy joke. The punch line was delivered beautifully but getting to the punch line was a bit dull. Maybe with each shot of the cowboy we see him getting more and more scared. Sweat dripping down his face, his eyes budging out, the pupils dilating, all leading up to BAM! the punch line. Nice short, very funny, I'd love to see more.
