No joke: these two flavours are better than any of their regular ice cream flavours. How does that make sense? No idea - ain't no physicist. They're insane tasting.
And I'm not endorsing them here as some sort of "better for you" choice when compared with ice cream. There's hella sugar in there and I'd bet that they're equally as bad as ice cream is for you. I'm really just here to tell you to try one (or both) of these immediately. I literally haven't bought any other flavour in the past... three years? Yeah. Maybe even four. MAYBE EVEN FIVE.
There's one other flavour in their frozen yogurt selection: vanilla raspberry. But don't get that one, it blows. The raspberry just ruins it, as raspberries usually tend to do.
Definitely try the vanilla or coffee, though. You'll thank you.
