The gang’s all here for “Grown Ups 2,” Adam Sandler’s latest lowbrow make-work project for all the ex-jocks, jockcasters, “Saturday Night Live” has-beens and other hangers-on he keeps on payroll.

It’s another pointless romp through Sandlerland — where the women are buxom, the kids have catchphrases and the jokes are below average.

Basically, the sequel to the hit “Grown Ups” finds our Hollywood pal Lenny Feder (Sandler), his wife (Salma Hayek) and brood moved back to his hometown. That’s where childhood pal Eric (Kevin James) runs a body shop, Kurt (Chris Rock) is a cable guy and Marcus (David Spade) has just learned he’s a deadbeat dad.

Apparently, Rob Schneider was too busy to do the sequel. (Probably as much a shock to him as to us.)

Unlimited Digital Access. $1 for 4 weeks.

We follow these clowns through a long day — the last day of school for their kids — as they reminisce at Kmart (where Tim Meadows ended up), feud with frat boys (Taylor Lautner is their martial-arts-mad leader) at the quarry that’s the town swimmin’ hole and find other ways to not quite grow up by throwing an ’80s-themed party that night.

The big message here: “You can’t back down from a bully.”

The jokes? Broad variations of “the dozens,” guys giving each other the business in elaborate, limp insults. Spade is “Betty White” because he’s old and his hair’s a wreck, Rock is “skinny Danny Glover” and James is “Crocodile Dumb-BEE.”

Farts, belches, poop and pee gags, guys leering at cheerleaders, women leering at male cheerleaders all have their place. As does every comic, from Norm Crosby to Colin Quinn, as an ice-cream vendor who gives a nice speech justifying Sandler’s entire farts-over-art career.

It’s dated, it aims low and Sandler is, as always, self-aware enough to get that he’s pandering.

At least the guy’s out there, stimulating his little corner of the economy. Sandler is one businessman who takes the president’s edict about make-work projects to heart. As deep as it gets in “Grown Ups 2,” you know the fellow loves his movies to be “shovel-ready.”
