How do you small talk and be funny?

Wit can't be rehearsed & studied it has to come natural you have to feel it.Anyone can give you a million funny lines it means nothing without you being apart of it OK First relax you're taking a test lol When someone's is remarking on any topic get a picture in your mind & put or add a twist to it & make it simple.Small talk doesn't have to always be funny either just adding your opinion or even asking a question is small talk Try initiating small talk yourself bring up a move music whatever just try it OK then go from there.You can do this Good luck & get chit chatting
