At first glance, it looks like a simple behind-the-scenes photo from Young Frankenstein â Gene Wilderâs intense stare, Marty Feldmanâs mischievous grin, and that classic Gothic lab backdrop. But if you look closer⊠something doesnât add up.

That famous image making the rounds online isnât the result of Photoshop trickery â itâs a real, unedited frame from the film. And the âblooperâ hiding in plain sight is one of the funniest (and most brilliant) Easter eggs in comedy history.
Sharp-eyed fans noticed it years later: Igorâs hump mysteriously switches sides. In one frame, itâs on his left shoulder⊠in the next, itâs on his right. No camera trick. No continuity error. Just Marty Feldman being, well, Marty Feldman.

As it turns out, Feldman improvised the whole thing. Without telling director Mel Brooks or co-star Gene Wilder, he decided to quietly move his hump from scene to scene â never acknowledging it, never breaking character. The result? A running visual gag so subtle that most audiences didnât notice it until years (or even decades) later.
When Brooks finally realized what Feldman was doing, he loved it and told the crew to leave it in. What began as an âaccidentâ became one of the most iconic hidden jokes in movie history â the perfect blend of chaos and genius that made Young Frankenstein a comedy masterpiece.

So no, that viral photo isnât doctored â itâs proof of a joke so sly it fooled generations of fans. Look again⊠the hump has moved, and now youâll never unsee it.
