"Pierre and Antoinne" joke

One day, as Pierre was sitting on his porch, he saw Antoinne coming down the road with a bag in his hand. "Hey, Antoinne! What do you have in the bag?" Pierre asked.
"I have cats in the bag," replied Antoinne.
"Why do you have cats in the bag?"
"I'm going to use them to catch the catfish."
"Antoinne! You don't use cats to catch catfish!"
"Wait and see, Pierre."
That evening, Pierre was sitting on his porch again and saw Antoinne coming back up the road with a bag. "Hey, Antoinne! What do you have in the bag?"
"I have catfish in the bag! I used the cats to catch them!"
The next day, as Pierre was sitting on his porch, he once again saw Antoinne coming down the road with a bag in his hand. "What do you have in your bag today, Antoinne?"
"I have rats in the bag!"
"What are you going to do with the rats?"
"I'm going to use them to catch the muskrat!"
"Antoinne! You can't use the rats to catch the muskrat!"
So later that evening, Pierre spotted Antoinne coming back up the road, dragging his bag behind him. "What is in the bag now, Antoinne?"
"I have the muskrat in the bag. I used the rats to catch him."
The third day, as Pierre was sitting on his porch, he saw Antoinne walking down the road with something in his hand. "What is that in your hand, Antoinne?"
"I have pussywillow!"
"WAIT! Antoinne, I'm coming with you!"
