An elderly lady walks up to the bar on a cruise ship and orders a Scotch with just two drops of water. As the bartender hands her the drink, she smiles and says, “I’m celebrating my 80th birthday today.”

The bartender, feeling generous, says, “Well, happy birthday! This one’s on me.”

After finishing the drink, the woman on her right turns to her and says, “I’d love to buy you a drink too.” The old woman gratefully responds, “Thank you. Bartender, another Scotch with two drops of water.”

“Coming up,” says the bartender.

Once she finishes that drink, the man on her left offers, “Let me buy you one as well.” The old woman smiles again, “Thank you. Another Scotch with two drops of water, please.”

“Coming right up,” says the bartender, now very curious. As he hands her the drink, he asks, “I have to know, why just two drops of water with your Scotch?”

She chuckles and replies, “Well, dear, when you reach my age, you learn how to hold your liquor. Holding your water, on the other hand… that’s a different story!”
