Hey, don't knock the worthiness about discussing the risks of salmonella.
This could be like how in the early 90s everything turned hip-hop format to try to relate with the youth to impart important information! Someone needs to make an TMNT themed/branded info poster about not kissing reptiles, or at least taking proper precautions.
Dang, if it was done vaguely in jest, I might buy such a thing.
April might consider using a plastic wrap barrier. Use protection against salmonella, April.
Edit: Also, the girl shouldn't have to take all the responsibility... he aught to at least use an antiseptic mouth wash.
