You do realize that 'fun' is subjective and humor is contrasted by personality right?
Sure, but i'm confident that there's some things out there that will get a high percentage of girls laughing and have been field tested.
Bit like there was some line about telling girl that they look lie the powerpuff girls i've seen in infields (I don't even know who the powerpuff girls are!) and the girls seem to crackup laughing like 9/10 times, and so every pua seemed to use that line again and again.
If I see a girl at a bar, my brain doesn't think anything 'funny' in relation to assumptions about her. I think ''she looks like she's waiting to meet a friend for a drink. Great'' whereas Tyler might use some funny canned line that gets her laughing off the bat which is what i'm after.
