I remember thinking “body double” when we saw them, since it was a cut away shot if memory serves.
I loved Stevie’s new chin and especially what happened to it.
In case anyone was wondering…April is part of the main cast of Mike & Molly. She is adorable 
Stevie (Steve Little) does a lot of voices on Adventure Time His main role is Peppermint Butler lol
Here’s Danny McBride on Kimmel, later joined by Steve Little. Good interview (in 4 parts, sadly)!
Yeah, it was a body double.
And Maria’s in the last few episodes were obviously prosethetics.
Now I’m craving some feeeeixins.
If you only know Steve Little from E&D, you should check out some interviews with him out of character. He’s a surprisingly normal guy. I did like that in the finale:
The movie version of Steve (even if it was imagined by Kenny) was played by a guy with Downs Syndrome.
