I find myself unable to come up with witty remarks in normal conversation and especially when I’m being made fun of.

I’m not a target that’s constantly being made fun of but I do get shit tested by guys and girls when I’m meeting a new a group of people. I’m a relatively big guy cuz I lift and have my looks/life together but I also get clowned on by my friends at times. One of my sticking points is being quick witted and clever. I have trouble thinking of a good comeback when I’m being made fun of.

I’m a comedy buff and I read a moderate amount. I’ve been told these two things help but I have not seen any changes since I’ve increased my comedy intake.

What are some concrete steps/exercises to developing a quicker wit?
