Didn't see the "No Repost" rule (stupid rule if ya ask me) so I didn't bother to thoroughly check if it had been done before.

I found the gif in my pictures folder with the filename watchthiswhilelisteningtotomsdiner.gif

I headed to gifsounds.com and Gifsounds is just like "hey bro, submit this to reddit"

And then I did. When you submit that way it doesn't show subreddit rules so I didn't realize it'd matter if it was a repost because hey, that's what votes are for.
