In 1981, The Dayton Daily News twice accidentally mixed up the captions for Dennis the Menace (American version) and The Far Side, making the family-friendly Dennis the Menace cartoon appeal to a more mature audience.
Far Side illustration: Three snakes (mother, father and child) sitting down for dinner. The grumpy child snake speaks.
Mismatched caption: Lucky thing I learned to make peanut butter samwiches or we woulda starved to death by now
Dennis the Menace illustration: Dennis and a friend carrying sandwiches walk past Dennis's mother, who is busy talking on the phone. Dennis speaks.
Mismatched caption: Oh, brother! ... Not hamsters again!
A few weeks later the same kind of mistake was repeated...

: Two neanderthal
s are in a cave: a fortune teller
with a crystal ball, and her customer. The fortune teller speaks.
