Two friends were out fishing when one of them suddenly had a heart attack and fell into the water. The other friend quickly jumped in and saved him, performing CPR until he regained consciousness.
The rescued friend gasped for air and said, "Thank you so much for saving my life! I can't believe I almost died out here."
The other friend nodded and said, "Yeah, it was pretty touch and go there for a second. But don't worry, I know CPR."
The rescued friend chuckled and said, "That's great, but I have to admit, I was a little worried when you started performing CPR on me."
Confused, the friend asked, "Why? What's wrong with my CPR?"
The rescued friend replied, "Well, for starters, you were singing 'Stayin' Alive' by the Bee Gees the entire time."
