The other day at work, I was talking to an ABDL friend of mine about Disney movies. At one point in the conversation, she said "I think the last time I saw Beauty And The Beast, I was wearing a diaper."
To which I responded with "So... A couple days ago."
She laughed and said "Damn, you beat me to my own punch line."
It's just kind of funny how dumb diaper/baby jokes like that can be said in public as just that, yet carry more humor if you're ABDL aware.
