Possibly the stupidest hand I've ever seen. Fold pre?

2/5, $1k max, 9 handed.

Hero - UTG+3, ~$1200, MAWG. TAG. Never limping. Not much flat calling pre. Mostly raising or folding pre. Aggressively check-raising flops, over-betting turns, and going for max value on the river. Playing well and seems to have a solid table image. Showed one huge bluff a few hours earlier, but not getting out of line much, if at all.

V1 - UTG, ~$600, middle-aged Asian Indian fellow. Recently joined the table, maybe 2 orbits earlier. Seems stabby-splashy-spewy - lots of limping/flatting pre, not much raising/3B'ing, mostly flat-calling post-flop, with both strong and weak value, sometimes stabbing when action gets checked to him.

V2 - HJ, ~$230, MAWG. Stuck on the session, typical loose-stabby rec-fish. Has seen hero get max value with his monsters as well as make huge bluffs. Never believes hero or anyone else has a hand unless he sees it, so calls down pretty wide. Equally prone to over-playing weak value and slow-playing thick value.

V3 - BTN, covers everyone. Asian kid in his 20's. Opening lots of pots and calling raises from LP or the blinds, occasionally 3B'ing, and frequently luck-boxing his way into winning big pots. Apparently doesn't want to play hero on later streets, based on his table talk and his making some nonsensical, overly-aggro plays in weird spots, like turning semi-strong hands into massive over-bet bluffs in way ahead / way behind situations on flop or turn.

OTTH:

V1 in UTG limps, one other EP limp. $17 in pot.

Hero in UTG+3 raises to $35 with 76dd.

V2 in HJ calls. V3 on BTN calls. Blinds fold. $122 in pot.

V1 in UTG back-3B's to $135. $252 in pot.

Hero in UTG+3 calls. $352 in pot.

V2 in HJ back-4B-LOL-jams for $230. $482 in pot.

V3 on BTN back-5B-WTF-jams, covering everyone.

V1 calls the jam for his last $465. Not exactly a fist-pump snap-call. More like a "I probably messed this up, but can't fold now" insta-call.

Hero has $1065 behind. Not sure if I'm doing the math right, but I think the pot is $2642 before I call, laying me 2.5 to 1.

So...yeah, never been here before. Maybe I should have folded to V1's 3B (or 4B?), but...

76s can't possibly be the best hand here, and every instinct I have said I should fold, but it doesn't look to me like V1 has AA, and even if he did, how strong can V2 and V3 be, the way they've played this?

Why do I think everyone here is pushing with the most marginal or downright insane BS, and I may not be worse than a 2.5 to 1 dog here? Should this ever be a call?

Will post reveal tomorrow.
