FBI Warning Screen
The FBI warning screen prank shows a full-screen federal-lock notice — official-looking seal, red "THIS DEVICE HAS BEEN LOCKED" headline, case number, and a live recording timer. It looks exactly like the ransomware-lock trope, but nothing is actually locked.
Press F11 for maximum realism. Tap or press Esc to exit.
Installed the crack fills the entire screen — no browser bar, no tabs, no giveaway.

For laughs only. Nothing here installs, downloads or damages anything — it's all harmless CSS/JS in the browser. It's a staple of April Fools' Day pranks and works any day of the year. Just keep it kind — see what makes a good prank.
