The line comes from SpongeBob SquarePants, the long running animated television series, where formal narrator and announcer voices are a regular comic device. Clipped on its own, the interruption began circulating on soundboards and in meme edits as a ready made break in programming. It sits alongside other long running SpongeBob quotes like the my leg gag, which fans reuse out of context for years. Its popularity comes from that reusable format, since any creator can place it before their own announcement and borrow the show's deadpan timing.
