On a nice summer evening, Paul, Jim and Harold went fishing at the lake. Suddenly, Paul starts struggling and pulling.
"That's gotta be a big one!", he says.
With a strong tug, however, Paul is pulled from his feet and falls in.
After a minute, he hasn't resurfaced, leaving the other 2 men utterly confused.
"Maybe we should pull him out", Harold suggests. "Good idea", says Jim, and they jump in, pulling the motionless body out.
"Oh no", says Jim, "he passed out, we gotta do CPR!" "Okay, i'll do the heart massage, you keep him breathing", Harold said.
and with that, Jim began doing mouth to mouth, in order to fill Paul's lungs.
After a few seconds, he stops, heavily breathing, and remarks: "Harold, i can't continue this, his breath is so terrible!"
Harold replies: "an unpleasant smell prevents you from performing CPR? let me try", and promptly, they switch places.
After a few breaths, Harold too cannot continue. "You're right!", he exclaims, "it's unbearable! What on earth did he-"
"Wait a second", Jim interrupts his rant. "That's not Paul! This Guy is still wearing Ice Skates!"
