It was Bob and Mary's 50th anniversary. As they sit at the breakfast table, Mary looks over at Bob and says, "Bob, 50 years ago just looking at you made my breasts hot and tingly. And 50 years later, it's the same. I look at you and my breasts still get hot and tingly!"
"Well, I'm not surprised," growled Bob, "One of them is in your coffee and the other's in your Alka-Seltzer."
Badda-boom.
