Mario bending Dale\'s ear!!
 

I.e. bitching about Belinda!! He hates Dale! but he is trying to plant doubt in his mind!

There's a weird part of me that wishes that these sh1t stirrers Mario and Luke would just own up to what they're doing to the diary room and thus the general public.

That way, it would be obvious to us that they're aware of what they're doing, acting so on purpose simply for the camera, BB, the audience and not because they are malicious to the bone.
