A woman is walking on a beach in Texas carrying two Redfish in a bucket. A game warden walks up and asks to see her fishing license.
"I don't have a fishing license," says the woman.
"You know it's illegal to fish without a license, right?" asks the warden.
"I wasn't fishing, officer. These Redfish are my pets."
"Yes, officer. They like a little exercise, so when the weather's fine, I take them to the water and let them swim around. Once they're done, I give them a whistle, and they jump back into my bucket, and we head home."
The officer isn't buying a word of it, so the woman says, "Don't believe me? Watch!" and she throws the fish into the sea.
The warden waits for a minute, then says, "Alright, now whistle to your fish and make them jump out of the water."
The fisherwoman turns to the officer and says, "What fish?"
