-So I the only vaccination I have left is Hep B, but there�s yeast in it, which I�m allergic to. So I have to get a note from my allergist saying they can give it to me.

-How do you get Hep B?

-That�s the thing, it�s like, body fluid exchange. I don�t plan on engaging in a lot of that.

-True.

-But apparently you can get it by, like, sharing someone�s toothbrush or razor. Though I also don�t plan to approach random strangers and ask them for their toothbrush.

-True, and it�s not likely someone is going to come up and spit in your mouth.

-You never know.

-That might be a local custom.

- Right. You�re in some remote little town, surrounded by a group of angry villagers who are offended that you won�t engage in the local custom of spitting in each others� mouths as a friendly greeting.

-But I didn�t get my shots!

-They�re all screaming, �Spit in my mouth! Spit in my mouth!

-You�re cursing the guidebook authors.

-�Spit in my mouth! The gods will be angry!�
