Sometimes you show up to a job without any of the necessary tools, but that's no excuse not to do the job. It's not like there aren't a dozen other microphones in front of the guy's face. I'm pretty sure it won't be hard to get the audio of what he said, right? All those microphones are just for advertising anyway. God forbid you forget about ESPN or Fox.
One of my favorite jokes is using a weird object as a microphone or a telephone. It's no one else's favorite joke, but it sure is mine. At any awkward moment I'll just pick up a show or a banana and say, "hello?" If that doesn't get a laugh and turn things around, then I don't know what will. Quite obviously I don't know what will.
