"Your total today is one big family hug" - oh my goodness, that little girls giant smile in the edit, you got me McD's. You bastards, you got me. That's adorable. Right in the feels.
Careful with the "call your mom" tactic, though. Call her to tell her that for a packet of free fries? That's selling your mom quite short, isn't it? And what if she's no longer with us? I can see this backfiring a lot.
