It really isn't funny, it's just stating the obvious. The first thought of 90% of men who see that he had his right hand cut off would be, man will he have a hard time masturbating.
Being a kid of the internet generation, i quickly learned that you can view twice the porn and keep your mouse clean of dick if you don't shift hands for fapping and browsing
when i was a child i thought using my right hand was making my junk bent so i started using my left and now im used to it and im really glad too because i dont have to switch up hands when looking for porn
