Fishing on the back large catch

The husband came home from a day's fishing and tossed an empty creel on a chair. His wife looked at it and then said, "Didn't you go fishing today?"

"Yep," answered the husband.

"Didn't you catch anything?" asked his spouse.

"Sure did," replied the fisherman. "Hooked a fish so big I couldn't haul it into that boat."

"What happened, then?" asked the wife.

"Heck, the darn thing pulled me right over the side," answered the fisherman.

"Then why aren't you soaking wet?" asked the puzzled wife. "Because I landed right on the fish's back!" shouted the fisherman.
