Are You Sure About That?

Born on June 29, 2016, in a Cricket Wireless hidden camera prank video, "Are You Sure About That?" entered the world with all the subtlety of a steel chair to the face. The premise was simple: unsuspecting fans would make bold claims, only for John Cena himself to burst through a paper wall, theme music blaring, demanding they reconsider their confidence.

Within two weeks, the original video had amassed over 13 million views. But it wasn't the prank itself that achieved immortality—it was the green screen isolation of Cena's incredulous delivery. Vine editors seized upon it immediately, splicing the Champ into everything from political speeches to movie trailers. Saw someone online claim they'd never lose? Cue the trumpets.

The meme found its spiritual home alongside its older sibling, "Unexpected Cena," creating a one-two punch of wrestling-based reality checks. One memorable edit inserted Cena into footage of Bill Clinton denying the Monica Lewinsky affair—a collision of scandal and skepticism that proved irresistible.

But Vine's shutdown in January 2017 dealt the format a body blow it couldn't recover from. Without its primary ring, the meme limped into Twitter and YouTube but never recaptured that explosive energy. The clips exist, the green screens remain, but the spontaneous combustion of a perfectly-timed "ARE YOU SURE ABOUT THAT?" became a relic of a more chaotic era.

You can't see him. But you can still hear the doubt.
