Two classics from the touring musos’ repertoire:

A trumpeter has enjoyed a convivial night out after a gig. Staggering back to his hotel in the small hours, he manages to recall that the band has an early flight, so (congratulating himself on his clear-headed practicality) he walks unsteadily up to the receptionist and asks her in suave yet slurred tones,
“I say, would you be so kind as to book me an alarm call for 6.30?”
“Certainly sir,” she replies. As he staggers off she calls after him,
“Um—you do know it’s 6.45?”

And one about another trumpeter:

After a gig in New York, he’s fast asleep when the phone rings.
A jaded voice drawls,
“Did you book a wake-up call?”
“Oh, um… yeah.”
“Have you had it yet?”
“Er… No.”
“Well, WAKE UP.”
