In the BBC adaptation of Jeeves and Wooster, Wooster is
singing Minnie the Moocher and trying to induce Jeeves
to join in.

It's pretty funny when 'Sir' says something to the effect
of "It's sort of a call-and-response thing, Jeeves, I sing
one line, and you sing it back to me."

Whereupon he sings

Ho-de-ho-de-ho-de-ho!

And Jeeves responds, spoken, as slowly and dryly as ever

Ho do oh dee ho dee ho, sir.
