How's this for an ultimate TV throwback? Right at the peak of Fresh Prince of Bel-Air's run — October 1991 — NBC threw a little cross-promo in on one of their other popular sitcoms, Blossom. In the episode, "I'm With the Band," title character Blossom Russo, played by current Big Bang Theory star Mayim Bialik, meets Will Smith while on a band trip, and has an… enthusiastic reaction.

The full episode is playing Friday night on the Hub Network. Set a reminder with NextGuide so you don’t forget to tune in!

Don't miss the episode.

Fresh Prince was just beginning its second season when the episode originally aired, and young Will was a full-blown heartthrob — so naturally, Blossom and her best friend Six LeMeure (Jenna Von Oy) are stoked when they hear a rumor he's staying at the same hotel as them. Blossom's run-in with Will comes after a weekend of ill-advised hi-jinks that are worth a watch on their own. Plus, bonus: Six raps the Fresh Prince theme song at one point.
