Spell It or Eat It

Sometimes typos appear in comic strips.

Above is the Garfield of February 13, 2019, as it appeared in the Oklahoman.  Since I never before ate a "hamburer," I decided to check online.

Do you suppose somebody at the local paper re-lettered the comic incorrectly?  Alternately, was the misspelled version the "original," distributed version?  How could that be so -- I mean, don't bigshot cartoonists have proofreaders?

'Tis a mystery.  See you Thursday!
