Here’s Johnny!

 xdyJV-lXkcw A common Stock Phrase, said when Lampshading somebody's entrance. If you're announcing yourself this way, either you have no friends to announce you or you have a big ego. If you announce somebody else this way, you're drawing everyone's attention to the other person's big entrance.

Occasionally found as a bad guy's Pre-Ass-Kicking One-Liner.

Born from Ed McMahon's Catch Phrase “Heeeeeeeeere’s Johnny!” on The Tonight Show, it was made popular and haunting when used in the film The Shining by Jack Nicholson. Since then, it had made its way into popular culture as a trope all its own, occasionally with different names replacing "Johnny".
