I went to ireland two summers ago. Took a tour around the island, spent a week in dublin, and two weeks in london afterwards.
On the tour when we went to blarney castle, i noticed how touristy it was. All the local irish thought the whole myth about the blarney stone was just silly and so did I. So when it was my turn to kiss the stone, I decided to make it count. I pecked it teasingly once then went in for the kill. It was a whole 45 second long kiss with lots of slurping and lots of tongue. ALSO the blarney stone IS NOT SET UP ON A PEDESTAL OR ANYTHING. ITS ACTUALLY A STONE IN THE WALL OF THE CASTLE THAT IS HANGING IN A BIG CRACK. Two people have to hold you so you don't fall. In fact a few months before I got there a tourist DID fall down and break her arm.
so they installed these bars below it so even if you do fall you'll just smack your head on the bars. The two guys holding my feet got pissed off at me for being "lude" with the stone.
Totally worth it though.
