It's different for every type of girl. Some of the more outgoing girls will like the jokesters, while the more timid ones like the more laid back guy. However, that can also work the other way too. I'd say I am somewhere in the middle because I am a jokester, but I'm laid back, which I'm happy to say works out for me because I'm being myself all the time. :D I've been told a lot of girls at my school like me because 1.) I'm polite 2.) I'm funny 3.) I'm not loud talking and constantly cracking jokes. 4.) I am laid back and act cool under pressure.
So no, you do not have to be the loud talking jokester who practically begs for attention; instead, girls can like people like you. Crack a joke once in a while, but don't overdo it because honestly, no one likes a guy who always jokes around about everything.
Just be yourself, that's the most important thing. Acting like another person and trying to be the "attention getter" is not going to help you at all because people will wonder what has gotten into you and will make it worse for you. Good luck! :D
