Ball Chair Puns

So my sister brought her computer over for my dad to fix. From my room, some 30 minutes later, i just heard him sniggering, and eventually balling his eyes out with laughter. He summons me over, and says through teary eyes "Look what i changed her computer name to!" So, look i did, expecting something silly. Sure enough, he had called it "Banana". I just shook my head and walked off while he cackled maniacally in his chair.
