That was not exactly what I would class as a 'humorous' advert, certainly nothing that would make me 'lol'. Mildly cute, yes, but that's about it, and it really peters out during the morning scene.
Would have been better had the dog joined in with the animals, or at least if the girl had joined in with the dog on the trampoline. Everyone staring open-mouthed at it without smiling just ruined the cheery feel that the advert should have had... why couldn't they have made it so that the parents have smiled, laughed and put an arm around each other after the initial shock as they watched their daughter and dog bouncing joyfully together?
Meh.
