Should I be worried about his mouth sore?

If I share a brew with a buddy and he has herpes or HIV or something like that, can I catch it too? The thing is that last night I accidentally drank from a friend’s beer bottle, and today he has this odd looking mouth sore… It’s freaking me out!
Should I be worried about his mouth sore?
Yes, worry… The Gods tend to punish those who steal other people’s beer. In Viking times you would get your arm chopped off if you drank of a man’s last alcoholic beverage.
Make amends by sitting on a Viking helmet for a day. This should please the Gods, and prevent you from catching anything from your friend’s horrific sore.
