Back when I got my first phone you could text from i text my son a question. He text me back IDK, puzzled I text back, what does that mean. He texts I don’t know. I text what do you mean you don’t know you texted it to me. Been a running joke on me since
Who's on first? I don't know. THIRD BASE!
( actually, Taxi's "slow down" sketch might be closer, lol).
