IKEA chairs.

I assisted a photographer on a photoshoot for which he bought an IKEA table and chair to assemble as props. 

Table? No problem. 

But when we got to the chair, we absolutely could not put it together. After struggling to figure out how everything fit together, we spent another ten minutes trying to insert two screws into the underside of the chair, with no luck. 

And so we call over an instructor who was doing a photoshoot a few sets away from us. He puts in both screws in less than two minutes. 

"You know what we learned today? We'd be the worst newlyweds ever."
