What is the difference between my Gun and my Dick ? Both of them kills, but I stop using the gun after the death .
Why? What do you mean by that? It sounds sexually too dark to me how you worded things here.
I kill someone but I'm not using the gun anymore. It's a joke, it's just a joke.
The joke here is on you, this is in bad humor. Making it seem no big deal about rape and murder is going to be too tasteless for others to handle. Using more of a tactful slant of humor will make more of the right people laugh.
