Diet Coke TV Commercial, 'Because I Can' Featuring Gillian Jacobs
After reaching for a Diet Coke in a fridge full of colorfully labeled cans, actress Gillian Jacobs explains that the drink makes her feel good. She says life is short and you should do what you want, encouraging dreams to "yert it up" or run a marathon ... even though the latter sounds super hard. And, of course, if you're in the mood for a Diet Coke, she says, have one and just do you. Diet Coke has put a twist on its original taste with a collection of flavored sodas.
