A piece of chocolate-covered bacon may … have been the greatest thing I’ve ever tasted.

There’s the punctuation of Standard Written English, and then there’s nonstandard punctuation that signals an informal, conversational tone. The informal commas in the last sentence bend the standard rules.

Lighthearted journalism is one context. But in business writing, nonstandard punctuation can lower your credibility.

Adding the word and to the quotation’s last sentence would keep it informal, but make it impeccably standard: “Bacon coffee, bacon cereal, and bacon ice cream — America, cut it out!”
