"Incredible Hulk" Burrito, and other secret menu items

So the other day I found out about the Incredible Hulk burrito on our "secret menu" and after trying it (it's literally just a beefy five layer with guac instead of nacho cheese) it's not terrible. Solid 7/10. Have y'all had it?

But I am curious about other secret menu items, especially in these months with no more fries, what cool shit can I make when there is a short window of time between orders?
