I did something embarrassing while getting drunk for the first time?

Well I'm in college and I just turned 21 2 months ago and well yesterday my friends just invited me over and we just had a small get together with about 10 people for fun and well all they had to drink was beer. And I know this sounds stupid, but I had never drank before, but I didn't want to tell them, because I didn't want to sound like a goodie 2 shoes so I just got a can of beer and lied, "It takes a lot to get me drunk!" And then 1 small 12 oz beer can later I'm drunk as heck! And everyone else had already drunk like 5 cans and they weren't even mildy drunk. And everyone was saying, "Your slurring your words! Are you drunk already?" And then I drank a 2nd can of beer and halfway through it I started not thinking and my friends filmed me and I kept on saying random things! Like I danced and said, "PENGUINS! PENGUINS! Ahhhh! Penguins!" And I don't even remember doing that! And then they showed me drinking a 3rd can and I'm sitting on the floor and I'm saying in a drunken voice, "Look I'm a cow! Quack quack! Ribbit!" And now everyone thinks I have problems, but that was the first time I've ever been drunk! Have you ever been this drunk from just drinking 3 12 oz cans of beer?
