I was watching Foster's home for imaginary friends, and there was a speed racer reference.
Foster's home for imaginary friends is a show made in the early 2000s, and speed racer was made in the 60s. Actually, speed racer is a 60s anime
Probably pretty obvious which is which based on image quality

Uh... I've watched all of season 1 of speed racer since I have it on a disc
Probably why I'm so excited about the reference-
I always get excited when there's a reference to another show I know for some reason ._.
