What advice is there for guys that aren’t funny or do they need to improve their looks/lose weight?

I’ve tried telling these jokes to people and girls that I liked and I feel that it’s not working partly because I’m overweight or unattractive:

”Why are 18-wheelers so expensive?” The prices are rigged

“What do you call a failed job interview for a waste management position? A waste of time

“The prices of bread went down, it’s a-maize-ing”.

I feel that if I were a Chad or taller, people would laugh at those jokes. I’m at least trying to be kind and sociable and don’t stay at the house all the time. Although I disagree with a lot of incel talking points, what they say about the Halo Effect (attractive people assumed to have personalities) is spot on.
