New Line Cinema has unveiled the first TV spot for Ben Falcone's upcoming comedy Tammy. Melissa McCarthy stars as the title character, who has an extremely bad day and decides to take a road trip with her crazy grandmother. Watch as she goes on the run after robbing a fast-food joint and catch it in theaters July 2nd.

Tammy (Melissa McCarthy) is having a bad day. She's totaled her clunker car, gotten fired from her thankless job at a greasy burger joint and, instead of finding comfort at home, finds her husband getting comfortable with the neighbor in her own house. It's time to take her boom box and book it. The bad news is she's broke and without wheels. The worse news is her grandma, Pearl (Susan Sarandon), is her only option-with a car, cash, and an itch to see Niagara Falls. Not exactly the escape Tammy had in mind. But on the road, with grandma riding shot gun, it may be just what Tammy needs.
