Some jokes are perennial, lasting for decades or centuries with minimal revision. Others have specific expiration dates. In this series, I revisit jokes that can no longer be told.
Q: What do you call a dog with wings?
A: Linda McCartney
Expiration date: April 27, 1981, when the last incarnation of the band Wings broke up.
Rather harsh on the late Mrs. McCartney, but beautifully structured in its simplicity. Unlikely to ever be recycled, as even if another entity named "Wings" arises that has people affiliated with it, the use of "dog" for an unattractive woman is in decline.
