Censoring the bad shit that happened before is a sure way to repeat it. See holocaust denial for the extreme. Don't deny talking about the past just because it hurts.
Yes but it wouldn't be funny if they just said "Heh, elevendon". It need a delivery sandwich. Maybe there's a funnier sandwich though.
