Who used "What's the capital of Ohio" joke first?

I've heard this joke a few times, & I was wondering what sitcom used it first.
I heard it on a Glee promo (don't worry, don't watch the show), I also heard it on Hot in Cleveland (just walked in on it), but I first heard it on Fresh Prince of BelAir (watch the show, BIIIIG fan).

Does anyone know if someone used it before them, or are other shows copying of Fresh Prince cause it's so awesome and many want to be as popular as it once was?

It was used on Vicar of Dibley in 1998. Don't know about other shows; I just assumed Glee was ripping off VoD.
