Jimmy Fallon's new holiday children's book, 5 More Sleeps 'Til Christmas, is out on shelves now, so the late-night host paid a visit to his local Target store to pull a total Justin Timberlake move and sign a few copies. In the beginning of the video Jimmy posted to Instagram, you can hear him say, "I saw my friend Justin do this," which is of course referring to JT sending fans on a wild goose chase to find one of five signed copies of his album Man of the Woods in February 2018. And seeing as Jimmy and Justin probably think only about each other all day, every day (OK, maybe not, but they sure do love each other), it makes total sense that Jimmy would follow in his best friend's footsteps.

With his 6-year-old daughter, Franny, acting as a "lookout," a gloved Jimmy pulled a marker out of his pocket and signed four copies of his picture book. At one point, he looked up, mentioned the manager eyeing him, and nervously giggled, which is possibly one of the most Jimmy things we've ever witnessed.

"Did a super secret book signing at @Target while we were Christmas shopping (Franny was the lookout🕵🏼)," Jimmy captioned the video. "Go grab a copy between tomorrow and December 16 at Target... and @faoschwarz will donate a toy to a child at @StJude for every book sold."
