The best thing about dogs (and kids, for the most part, too) is that they're themselves no matter the situation.
A dog doesn't care if you're in the supermarket. If they wanna bark, they're gonna bark. They don't care that the leather couch they're tearing up cost $3,000. They don't care that the mailman comes by every day because they're going to bark their heads off to protect their family regardless.
And if the dog is on a live TV broadcast, they don't care that a camera is staring right at them, they're going to sneak a snack without anybody noticing. Like this heroic pupper who didn't let anything get in the way of their meal. Just watch for yourself and see the master sneak-thief in action.
