Chimpu outside the cage

How does a short guy feel when he meets a tall person?” asked my colleague.
“He will feel the same way a bald person does when he chats with a long-haired dude,” I replied.
“I can tell you how an intelligent person feels when talking to a fool,” he continued.
“How?”
“The same way I feel right now talking to you,” he pulled my leg.
“I remembered and missed you yesterday evening,” I changed the subject.
“That’s sweet of you,” he was pleased.
“I was in the zoo,” I took my sweet revenge.
“Oh, was that you outside the chimpanzee’s cage at the zoo?” he continued.
Before I could reply, he snapped: “Someone was commenting the chimpu’s out of the cage and a man locked inside.”
