With the discovery of the existence of this amazing tool of the future, it’s apparent that Europe’s buns don’t always work as designed.

“Yes, sah, may I help you?”
“I bought two Big Macs, and me buns don’t work.”
“Oy. Bun problems, eh? I’ll fetch the Bun Trouble Shooter. One moment… There you go, sah! Good as new. Had to tweak the heel/club heights a bit. Should be tickety boo now, sah.”

Whew. That was a close one. If it weren’t for modern technology like the bun diagnostic tool, we might have had an irate customer on our hands. Instead we have an Overnight Open Thread.
