How about:
Pay More In Mass!
-Kennedy Country (Welfare, Drugs & Booze)!
-Come to Boston-See What $15 Billion Bought You!
-Welcome to Taxachusetts!
-Move To Mass-$500 Sign-On Bonus!
The only suggestion I have is based on my only personal experience in MA, me being a lifelong Southerner who makes occasional trips to places I’ve heard are good for drinking or learning new wrestling holds. But I do know how to spell the state’s name. Anyway:
Massachusetts: Change planes at Logan.
Massachusetts - We haven’t burned a witch in years
Massachusettes - Ph-nglui mglw’nafh Cthulhu R’lyeh wgah’nagl fhtagn eh-ya-ya-ya-ya ekka ekka Y’bthnk rnlzaytl Yog-Sothoth…
Massachusetts: Algonquin for “Land of Funny Accents”
Massachusetts: Pahk Your Cah In Hahvahd Yahd
Massachusetts: The Kennedys are almost gone, we swear!**
