Columbo: Grand Deceptions1989

Colonel Frank Brailie:
The sexual life of a camel is much stranger than anyone thinks.

General Padget:
He lies on the bank of the Nile and tries to make love to the Sphinx.

Colonel Frank Brailie:
But the Sphinx is only a statue...

General Padget:
...Beset by the sands of the Nile.

Colonel Frank Brailie:
And thus explains the camel's hump.

General Padget:
And the Sphinx's unscrutable smile.
