Study up on your germ prevention! ;P
Adults and children (excluding babies since they don't know better) shouldn't be putting their hands in their mouths anyway unless they've washed them first.
Btw, I wasn't serious about nuking the black rock due to the germs when I said it. That would be overkill but I personally wouldn't kiss that black rock nor the Blarney Stone due to the germ factor.
Neither would I.
Have you ever lurked at DU?
That place is so vile. I actually saw people claiming that the world should be more upset since we have killed more people in Iraq than so far have died in Asia.
Serious. These people are sick.
Blarney castle docents chuckle in the local, after work, about pissing on the Blarney tone after tourist hours. So yeah... I wouldn't kiss it either, but not because others had kissed it!
