A rare old bird is the pelican.
His bill holds more than his belly can.
He can take in his beak
enough food for a week.
I’m damned if I know how the hell he can!
I first heard this in the Columbo episode The Conspirators (1978), the “finale” for the show before it was revived 11 years later. https://instagr.am/p/Cnmsjp5t5Fe/
