Does he have a mirror?

He's the one who taught wild animals to play and have fun, so yes.

The real question is... does the sense of humor have a God?

Yes he does. When I was a teenager riding the school bus there was a mentally challenged young girl whom also rode the school bus to go to her special class.
I asked myself in my head "Jesus what would sex with that be like?"

Decades later and after 2 divorces I have came to realize Yes God has a sense of humor.
He showed me what fawkin re. TaTaTa people feels like.

of course, i exist after all right?

Yeah he does, last time i saw him he was trolling some dudes on 4chan and i think it probably counts
