Guy walks into a bar...
...and asks the bartender for the WiFi password.
The bartender replies, "you need to buy a beer first."
So the guy buys a beer, and asks again, "what's the WiFi password?"
The bartender replies, "you need to buy a beer first, all lowercase, no spaces or punctuation"
The WiFi password is fourwordsalluppercase
WiFi password at my parents house is still "It's a secret" so when people ask, we can tell them It's a secret.
