Little Johnny and two of his friend were bragging about how tough they were. "I'm so tough", said Bobby, "that I can wear out a pair of shoes in a week".
"Well", said Billy, "I'm so tough, I can wear out a pair of jeans in a day".
"That's nothing", said Little Johnny. "When my parents take me to see my grandma and grampa, I can wear them out in a hour".
