Dish Network is still promoting its “Hopper” video recorder with a series of ads featuring a Masshole family yelling at each other. Now it appears the company is trying another tack: a YouTube ad with Vince Wilfork attempting to affect a Boston accent. It’s a truly awful attempt. Half the time it sounds like he’s doing some sort of Caribbean patois. As any Boston person will tell you, you shouldn’t even try to replicate their accent. No one gets it right, least of all SOME DAHHKIE.
