Him "singing" Mr. Tambourine Man, is funny, yet almost scary

I think he might be really a cartoon character who has somehow managed to slip into our dimension and has tried to do impersonations of a human being as an 'actor' and 'singer', but he hasn't been able to shake away his real cartoon character essence.

And that may be his main quality.

He certainly doesn't seem embarrassed of how weird he comes off.

He probably doesn't notice it.
