I like this category of audio clip. It's not uncommon to hear those slip-ups at the tailend of a long day/leg:
"Westjet uhhh....what are we....?" *click* "Uh..Westjet xxx!"
Or when they're (bored enough?) mixing up the pronunciations/emphasis of ATIS idents:
"...and we have..pa-PAAA!" or, "...we have Wwwwhiskey!"
All in a day's laugh.
