These things never get old:
-Asking people to say something five times fast. It's better if it's not a tongue twister at all. "Hey, say 'butter' five times fast!" It's just fun to see who will play along. Plus, I'd rather not waste my time with a person who refuses to say something five times fast. What's your problem? I know you're saying it to yourself in your head.
-The pinky-finger and thumb "call me" symbol accompanied by the requisite whispered "call me."
A few reasons why I love this one. First, who decided that a pinky and a thumb was the best representation of a phone? Phone technology has come so far that most phones look more like the palm of your hand than anything else. But I bet you a dollar that if you held your palm up to the side of your head and whispered "call me" people would just think you were trying to talk about the person sitting next to you. Palm to the side of your head means you're trying to block out a secret. So I don't know if the phone symbol will ever be able to make the switch. It's this lasting archaic institution.
Another reason is that personally, I find the universal "call me" hilarious. When your awkward stage lasts from 12 to 27, the pinky-thumb phone is a nice way to make yourself laugh after failed attempts to talk to strangers.
"Hey, can I buy you a drink"
"Oh, OK. Call me."
Close-range exaggerated whisper with a symbol. It's not for everyone.
-And Rachel Maddow on any show. What's not to love?
