Seth MacFarlane’s raunchy R-rated Ted 2 isn’t generating the laughs everyone expected. The $68 million comedy, reuniting MacFarlane with Mark Wahlberg, eked out a third-place finish Friday, grossing $13.2 million from 3,442 locations for a projected $34 million debut in North America, well behind the $54 million launch of Ted in summer 2012. That leaves the race for No.
