"Careful What You Ask For" joke
Larry was just seconds away from receiving a vasectomy, when his brother and sister-in-law barged into the room holding their newborn baby.
"Stop! You can't do this!" exclaimed his brother.
"Why not?" Larry asked.
"Don't you want to have a beautiful baby someday, just like we have here?" his brother asked.
Larry remained silent.
His brother grew impatient, "C'mon Larry, I want a nephew. Make me an uncle, Larry."
Finally, Larry couldn't take it any longer. He gave his sister-in-law an apologetic look and asked his brother, "Are you sure you want a nephew?"
"Yes," the brother replied. "It would be an honor."
"Well, congratulations," Larry said, "you're holding him!"
