Man I feel so old and I am still 20..I think that my best years have already passed

Can we all notice that Lilo and Stitch are the common thread

KIM POSSIBLE AND LILO AND STITCH DID A CROSSOVER????
HOW DID I NOT NOW

Wait why is Jake long in the one picture twice?

Why wouldn't they, they still do crossover episodes I think

what about the Jetsons and the Flintstones?
