The line comes from Dexter's Laboratory, the Cartoon Network series created by Genndy Tartakovsky that premiered in 1996. Dexter, a child inventor with a secret lab behind his bedroom bookcase, was originally voiced by Christine Cavanaugh. His serious, accented self-introductions became a running signature of the show. Clips of the phrase later circulated on soundboards and in meme edits, where fans use it for overconfident entrances and nerdy character reveals, keeping the catchphrase alive long after the series ended in 2003.
