Bubble ring Puns

Just found this subreddit and, being a dad, I figured I needed to share some material...

I'm checking out at the home improvement store, my wife standing next to me as the bubble-headed cashier rings me up. She gets to a bag of six inch galvanized spikes that I was buying for an outdoor project. Trying to look up the price in her book, our ditzy cashier holds one up and says, "Is this nine inches?" I smile and turn to my wife saying, "Her boyfriend must love her. He's got her convinced that that's nice inches..."

At that point my wife slapped me saying, "You're disgusting!" and our little airhead just stood there and had no idea why.
