One of the funniest comedians I've ever seen used to do open mic nights to completely silent crowds. Joke after joke, silence. I thought she was hilarious, so I was always the only person laughing. She'd push through her set and end by saying, "Bye. I'm Tessy." in a low monotone before dropping the mic Chris Rock style and walking out. And then three people would look up from their coffees to clap.
I wish "Bye. I'm Tessy." was the universal way to exit awkward conversations. Just say it, drop whatever you're holding, and walk away.
The guys I used to work with spoke almost exclusively in their own created catchphrases. I once went through an entire 8-hour shift hearing only, "That's a good one, dude."
(To say this correctly, nod your head firmly on "good" and pronounce dude as "do")
This phrase can mean anything. It can mean that something really is a good one, like a joke or a suggestion, it can be a statement of acknowledgement, or it can mean that you have have no intention of doing whatever someone has asked you to do. Which is why hearing it over and over during a busy workday can be so hilarious/incredibly stressful.
The funny usually comes later.
The best part about a catchphrase is that all it requires is repetition. If you say it often enough, you can use it whenever you want. It doesn't necessarily have to make sense or apply to every situation, but if it happens to work out that way, that's a double bonus. This appeals to me on so many levels because I'm usually saying the wrong thing anyway. It'd be nice to have a tidy little saying to use in the following situations:
1) When I don't know what the people around me are talking about.
2) When I'm asked, "What do you think?" after I've drifted out of the conversation for a minute thinking about how cool it would be if those singing waiters from chain restaurants showed up on public transportation with cake and a fun birthday song.
3) When I have run out of things to say.
I'll have to think about it.
