Six credited writers and you get malapropisms such as 'It's all water under the fridge,' and 'That's just a suburban legend!' Carrey ensures that he gets almost all the funny lines here. Harry looks over 20 years of mail his parents saved for him. The Farrellys, who peaked with the raunchy, rude and yet romantic 'There's Something About Mary' in 1998, hurl miss-or-hit sight gags and throw-away lines at us. So the 50something '10-year-olds' motor to Maryland and then El Paso in search of the dopey bombshell (Rachel Melvin, out of her depth) who might be his donor-daughter, a 'genital donor match.' His comeuppance? Harry enlists two groundskeepers to help him yank out Lloyd's catheter (after changing his colostomy bag, with his teeth, of course).ДЄnd they're off, doubling up on a Schwinn to visit Harry's estranged Asian parents and then the aged, bloated floozy (Kathleen Turner, enduring jokes about her current appearance) who supposedly had Harry's baby and gave her up for adoption, decades ago.

Harry visits a catatonic, bearded Lloyd in a rest home only to learn he's been the butt of Lloyd's 20-year-long practical joke. REVIEW: 'Rosewater' depicts battle of wills in Iranian prison

SHOWCLOCK: Get theater listings and times for 'Dumb and Dumber To' They're 'Stooges' in a post-'Hangover' world, and the staleness shows. Those fart-joke farceurs, the Farrellys, re-team with their stars and an equally aged supporting cast for a film of occasional funny lines, random uproarious sight gags and bodily function jokes, all scented with a whiff of sad desperation. Sure, it's only trickling down your leg and never comes close to reaching your heart, but warmth is warmth, right? Jim Carrey and Jeff Daniels energetically reprise their popular roles, and the warmth follows. Twenty years after they permanently lowered the bar on broad and dumb character comedies, Lloyd and Harry are back, 'Dumb and Dumber' than ever in 'Dumb and Dumber To.'ДЄnd within moments of the opening credits, you may find yourself overcome with sentimental warmth at seeing two 50something actors as characters that the years have not made smarter.
