Climb the walls

"OH, I SURE AM HAPPY TO SEE YOU," THE LITTLE BOY SAID TO HIS GRANDMOTHER ON HIS MOTHER'S SIDE. "NOW MAYBE DADDY WILL DO THE TRICK HE HAS BEEN PROMISING US."
THE GRANDMOTHER WAS CURIOUS. "WHAT TRICK IS THAT?" SHE ASKED.
"I HEARD HIM TELL MOMMY THAT HE WOULD CLIMB THE WALLS IF YOU CAME TO VISIT," THE LITTLE BOY ANSWERED.
