Honestly, what better odd couples from TV are the best way to describe the friendship between Rainbow Dash and Pinkie Pie, than the buddies of the popular late 80's and Early 90's television series Perfect Strangers.

I mean just look at the intro and tell me that it doesn't remind you of Pinkie and Rainbow Dash a bit ?

How in the hell are you old enough to know what perfect strangers was? I cannot believe that anyone on fimfiction other than my old kester would remember that crap.

Oh well, learn something new everyday. That being said, I think that RD and Pinkie are a bit more unhinged than those two. Oddly enough, it would be RD keeping the sanity in that relationship.

Probably why I love the ship so much.
