Regular Show Crossovers!

I was watching Regular Show and you won't believe what I found!!
if you want to see them for yourselves the cameos were in "Viral Videos" and "Party Pete".

The Banana from "Peanut Butter Jelly Time" or Banana Joe from "Gumball"




Guy from "Home Intruder"m.youtube.com/watch?v=hMtZfW2z…


And Rick(or Morty, can't tell which is which) from "Rick and Morty"


I love how Regular Show sneaks cameos in the backgrounds, I'm gonna watch some more episodes and see if I can find any more, tell me in the comments if I missed anything below...
