I know this ad is supposed to be funny- watching Joe Pesci get verbally abusive because a chip on his shoulder the size of Noah's Ark has been wobbled by a cute girl who isn't giving him 100 percent of her attention 100 percent of the time- I mean, what could be funnier than that?
Well, here's my take- "He isn't himself when he's hungry" is right up there with "you should see him when he isn't drunk" in the Encyclopedia of Excuses for Abusive Jerks. If the character in this ad is a touchy prick who throws a temper tantrum because a girl he just met at a party glances away from him while he's speaking, well, ladies...if you really like the guy, you can chalk it up to He Was Just Hungry He's Usually Really Nice You Just Have To Get To Know Him. But please don't come whining to me when it turns out that wow, what do you know, he's kind of a controlling, obsessive ass even when he HAS a Snickers bar.
Because people ARE themselves when they are hungry, drunk, tired, under stress, worried about That Promotion, On Edge Because It's the Playoffs, etc. etc. ETC. They are their TRUE selves. When they are sober, full, calm, satisfied? That's when the mask is securely fashioned. It's EASY to be a rational, polite, thoughtful human being when everything is just perfect. Thing is, in real life, there's never actually a time when everything is just perfect. Or anything.
So, Pretty girl at the party? Consider yourself fortunate- because for some reason the host decided to invite people to her house and then not put any food out, and as a result, you got a good look at this guy at his honest worst. Based on his attitude concerning your unwillingness to lock your eyes to his as he's speaking, I'd say you dodged a bullet. But if you want to ignore the fire alarms going off around you, I suggest you keep your handbag well-stocked with candy bars. And what passes as your brain equally stocked with "he only hits me when I provoke him" excuses. Good luck with that.
