How can I be normal? Please help!?

Okay so I'm really weird and I wanna be normal. Like sometimes, I randomly shout "PLATYPUS!" or "CORNDOGS!" or say some pretty random things but the only reason why I act like that is to entertain people and make people laugh... but people took it too far and boys started asking me out because of dares and people keep calling me lazy and it's making my self-esteem go low. Can someone please tell me how I can be normal? Thank you.
