"We need toilet paper."
"OK, let's get the Charmin Plus."
"No, let's buy the cheap stuff now and have my mom bring us Charmin next time she comes to visit."
"No, let's just get the good stuff. Our butts are worth it."
"Really?? Even though we're throwing money away?"
"We're not throwing it away. We're flushing it."
POSTSCRIPT - we got the Charmin Plus. Harley's mom didn't bring any the next time she visited.
