Anyone think Frank (Danny DeVito ) fought with some of the cast? In the earlier seasons Frank almost always sat at the center of the group in any shot, but as seasons progress Frank almost always is positioned at the edge or rather outer orbit of the group.

In Charlie Kelly: King of the Rats (Charlie's birthday episode the one with jeans chicken, worm hat gifts etc.) the gang viscerally hate Frank and I feel Dennis (Glenn Howerton) actually hates Frank (Danny) irl. He's called Frank a bitch several times and not in a funny way.

I think Charlie Day is the only actor who is actually truly friendly with Danny. Their friendship offscreen was evident in that SNL skit.

Then again in real life Danny and Rob and big bird hung out and watched the Eagles-Pats super bowl in Minneapolis.

Also I'm bored and just trying to stir up some drama, but I do believe there's something off between Glenn (Dennis) and Frank (Danny) both on and off screen.
