They clearly have the same sense of humor.

How well doSteve MartinandMartin Shortknow each other?

How many intricate details of each other’s lives can they recall on the spot at the same time?

Well, asJimmy Fallon’s Best Friends Challengeproved, not that many.

But they still showed us why they are indeed best buds.

They only got one exactly right.

“Complete this sentence: Steve has the world’s greatest blank,” Fallon said.

Both answered, “Collection of Nazi memorabilia.”

All of Fallon’s other questions fell through the cracks.

For example, “If Steve could be any liquid, what liquid would he be?”

Martin and Short have been popping up onThe Tonight Showover the years to appear in sketches andgenerally goof around.

So it felt like a good place to come on and talk about their joint project.
