Tim finally got to 5-years-old.
"Timmy nakey!" Kathy was shouting. "My favwit twin brother in the woold is nakey!"
"I guess we're twins," Timmy thought to himself. "Definitely unidentical ones."
"Why aw you nakey Timmy?" Kathy asked.
"You'we nakey too," Timmy answered, realizing he also lisped.
Finally, the parents came up to the room.
"Timmy! Kathy!" the mother said. "Why are you two naked?"
"Sowwy, mommy," Kathy said. "It was Timmy's idea."
"Is this true, Timmy?" the father asked.
"No, sir," Tim said, trying to sound polite.
"Timmy, everytime you say 'sir' you lie," father said. "I think you need a time-out."
"Stay in your room, Timmy," the mother said. "Kathy, you can go outside and play with your friends."
"Tanks, mommy," Kathy responded.
