When we last left Gracie Hart, she was the new hero of the FBI, crowned Miss Congeniality in the Miss United States pageant and freshly waxed from head to toe.

In “Miss Congeniality 2: Armed and Fabulous,” she is back working as a field agent who still snorts when she laughs — and who is still not very funny.

The sequel picks up three weeks after the first film ended. With her new status as a national hero, Hart (Sandra Bullock) and her superiors decide, since it is too dangerous for her to work as a field agent, the only solution is to exploit her fame and make her the new “face” of the FBI.

Within 10 months, she is more famous than Hillary Clinton and more accessorized than Carrie Bradshaw.

After Cheryl — Hart’s friend and refrigerated leftover from the first film — is kidnapped, Hart is sent to Las Vegas for a press conference on the matter. In tow is the angry Sam Fuller, played by Regina King, to act as Hart’s body guard, despite their hatred for each other.

What has been wrung out into the bottom of the cinematic barrel is the ubiquitous recycling of jokes, situations and characters, with the absence of the essential ingredient of humor.

Director John Pasquin has vastly underestimated his audience, expecting them to continually giggle at repetitive jokes about hairspray and lip gloss — yet believe and appreciate the fact that this woman is supposed to represent the FBI while fussing about her $30,000 Fendi luggage and whining to her J.Lo-caliber glam squad about her highlights.

The movie is little else than a list of fragmented and isolated comedic situations worked up by a team of writers, with the rest of the film serving merely as a vehicle to get Fuller and Hart through the list: one — tackle Dolly Parton; two — dress Bullock up as an old lady; three — get Bullock and King singing Tina Turner in a drag show with Diedrich Bader as backup. Yes, the situations are funny in and of themselves, but with no substance in between, and after a while the film begins to seem like a bad sketch comedy show.

Unoriginal, unrealistic and remarkably unfunny, “Miss Congeniality 2” is nothing more than another failed sequel.
