Kissing Blarney Stone
A group of Americans were touring Ireland.
One woman in the group was constantly grumbling: The bus seats are uncomfortable. The food is terrible. It's too hot. It's too cold. The accommodations are awful.
The group reached the site of the famous Blarney Stone. "Kissing the Blarney Stone brings good luck all your life," the guide explained. "Unfortunately, it's being cleaned today, so no one can kiss it. Maybe we can return tomorrow."
"We can't be here tomorrow," the cantankerous woman snapped. "We have another dull tour to attend. So, I guess we can't kiss that silly stone."
"Well," the guide replied, "it's said that if you kiss someone who has kissed the stone, you'll receive the same good fortune."
"I suppose you've kissed the stone," the woman scoffed.
"No, ma'am," the exasperated guide responded, "but I've sat on it."
