Very good, but last joke needs reworked.
You need, and I mean NEED to edit this. The splicer at the end should say "Nauuuggghty!" after the other one mentions a sexual inuendo for plasmid use. And sample the "naughty" from courage - use your voice actor for the other splicer. That would make this a solid ten, for sure.
As it is I give it a 7. The first two scene were too good (10 material really), I was laughing hard. The last scene had a bad penis joke when I was praying to god himself that you were going to sample courage and make him say "naughty!" after the other guy talked about using a plasmid in a vulgar manner.
Im looking forward to more of your work, because I did lol. ^^
