Funniest part was... there was no funny part.
I'd struggle to really even call this much of a parody. The only things really relating to Street Fighter are observations made by a million people before and since. Chun Li has thunder thighs! Guile's attack is Sonic Boom and the main theme to Sonic CD was also named Sonic Boom! Rufus is fat! HILARITY!
Well, actually, I guess that can be funny, but it needs good execution. In this thing it's just mentioned and then never followed up on. Umm... HILARITY!
And of course, just like Brawl Taunts, there's the constant use of internet memes with no real context or any real need for them to be there. Kanye West? Lost the game? The King of Hyrule? Really? Why not just throw in All Your Base and a big gay dance with them dancing to Numa Numa while you're at it?
And what was up with that... fast food place was it? What did that have to do with anything?
Really, the only difference between this and Brawl Taunts is that this uses Street Fighter characters instead of Nintendo ones. Besides that it's more or less the same level of writing.
Scoot's actually a pretty decent animator, so I'm giving it a few stars for that. Just too bad he chose to collab with someone whose writing makes Legendary Frog's look like comedy gold.
If anyone wants a good SF parody might I recommend Street Fighter Narration? It's short and simple but far funnier than anything in this.
