Seriously. Your first goal should be to come off as a guy who's openly being himself. Those funny guys you meet? Most of them are far beyond that point or grew organically from an early age.

I have never NEVER in my years of meeting people and making friends, known any guy who just "became funny" In fact. You might be surprised to find that girls will find aspects of YOU funny if you're simply being confident and congruent. They will giggle and laugh because guess what, everyone who's being themselves has some goofy aspects. Even you.

Guys who go push this funny guy game will always 100% of the time fall short because litterally anyone can tell a joke they heard on t.v. being funny is the LAST thing you should be going for. Focus on establishing natural energy levels first.
