"Kids and their operations" joke

There were these two kids in the hospital about to go in for operations..

Billy says to Bobby, "What are you here for?"

Bobby replied, "To get my tonsils removed, I'm really scared."

Then Billy said, "No tonsils is fun -- it's over fast and when you wake up u get a lot of jello and ice cream!"

Then Bobby turns to Billy and says, "So, what are you here for?"

Billy says, "Well I'm getting circumcised."

Bobby said, "Ouch I had to get that when I was born and I couldn't walk for a year!"
