"You're kidding, right?"

So the text exchange goes:
(Her): Photo of flyer for "Goat Yoga" and comment of "Huh?"
(Him): It's really a thing. And I'm signing us up.
(Her): That's the dumbest thing I've ever heard of.
(Him): I know. That's why I'm signing us up. Namaste!
.......long pause in response......
(Her): You're kidding, right?
Was I kidding when I said I ordered new checks with semi trucks on them? Nope. And I'm not kidding now either.
So guess what...Sarah and Dave are heading on a date!
To do Goat Yoga!
At a real, live goat farm in Wisconsin!!
All I know about yoga is that me and it are not compatible at all. But goats! I love goats! Enough that I'm going to yoga with them anyway.
Or they're going to do yoga with me. I don't really know. But we're going to find out because we're signed up for Goat Yoga! Hooray!!
