Now honestly with this comic I am not even sure I get what is supposed to be funny. Clearly it has to do with a robot you can have sex with, and apparently she thinks that welding a cherry stem (what would that even mean?) is an answer to the question of whether you can have sex with her, which it is not. Ha ha, silly robot! I guess then the "remove your pants" thing is supposed to mean "yes, this robot would like to have sex with you." So the cherry thing goes along with it.
I find this comic so unnerving in so many little ways. First off that its premise is "I don't have a human girlfriend so I got this robot, that's not weird." Then that the logical response would be "Ha ha, I just met your girlfriend so I'm going to ask about SEX with it/her!" I know Randall is really intent on this "incredibly open discussion of sex with casual acquaintances" but it's just stupid in practice. At least for a comic.
And then of course the "this is my girlfriend, and you asked an inappropriate question, and now she is trying to sex you up, why don't I just stand here silently." Just because that might be how you would act, randy, does not mean it makes sense.
Randall you have to draw better. You really do. You can't have your robots look exactly like people! You have to make them at least a little different. ok?
In short: This situation was all far too contrived to have any redeeming value.
What did I like about it: Honestly there were a lot of worse things Randall could have done and he wisely didn't. A "cherry" pun. Not having the character refuse robo-sex. Panel 3 shows he has put a little more effort into the art than usual.
