When Justin Timberlake appeared on "The Tonight Show" a couple of weeks ago, the singer exposed Jimmy Fallon as being one of those people who uses coffee mugs that have pictures of family members on them.

Timberlake secretly snapped a picture of him using the "Jimmy mug" and e-mailed it to Fallon.

Fallon then countered by presenting a mug that had a picture of Timberlake holding a mug with Fallon’s face. The gag wasn’t over there, though. Fallon then brought out another mug that featured a picture of Fallon holding the Timberlake mug, which featured a picture of Timberlake holding the Fallon mug.

If that confuses you (and it should), just watch the clip.

Anyway, this brings us to J.J. Watt., who posted this on Instagram Tuesday.

@jimmyfallon this showed up at my door yesterday… @justintimberlake

So, who will be person who gets a mug of Watt holding the Fallon mug, which has Fallon holding the Timberlake mug, which has Timberlake holding the Fallon mug?

Give yourself a pat on the back if you followed all that!
