A man goes into a bar in the airport and asks the bartender what the password is to their wi-fi.
Bartender: You need to buy a drink first.
Me: Okay, I'll have a coke.
Bartender: Is Pepsi okay?
Me: Sure. How much is that?
Me: There you go. So, what's the wi-fi password?
Bartender: It's you-need-to-buy-a-drink-first. No spaces, all lowercase.
