It took a couple of decades, but Elizabeth Banks is finally getting revenge for the most cringeworthy moment of her entire childhood, and on live national television, no less.

Elizabeth is making the rounds to promote her last big-screen outing as Effie Trinket in "The Hunger Games: Mockingjay, Part 2," but on "The Tonight Show" Thursday (Nov. 12), the topic of conversation was less dystopian mega-franchise, and more throwback family drama.

With her dad and sister looking on from the audience, E-Banks was invited to share the worst dad story she could come up with -- and let loose with the tale of a truly unfortunate incident involving a family road trip and an aerodynamic loogie.

EWWWWWWWWWWW.

Respect to Elizabeth's dad: He weathered this fairly humiliating moment like an absolute champion. Watch the whole thing unfold below.
