How To Summon The Double Rainbow Guy to your YouTube Channel

Put 'Double Rainbow' in your title and he will find  you!

The double rainbow might be summoning  you...

Update: Rip double rainbow guy, it was nice talking to you when you were around.

NFKRZ   can  also   be summoned (in a different way),  but he is  a bit unpleasant to deal  with, and I wouldn't recommend it.
