The program: “Seinfeld”

The plug: From Jujyfruits to Trivial Pursuit (“That’s not Moops, you jerk! It’s Moors!”), “Seinfeld” reigns as the king of quirky product citations. During season four, Kramer and Jerry are watching from an operating theater as surgeons mend Elaine’s ex-boyfriend. They accidently drop a Junior Mint from their balcony seats into the man’s abdominal incision. When George later asks Jerry how doctors missed the candy’s splash, Jerry explains: “Because it's a little mint! It's a Junior Mint!

Tootsie Roll Industries continues to sell Junior Mints, and the company’s website still recounts that seminal “Seinfeld” episode.

The program: “The Office”

The plug: The chain — best known for its double-entendre name and tightly-clothed waitresses — has been a favorite side joke for the merrily un-P.C. writers of “The Office.”

In season two, boss Michael Scott escorts Jim to Hooters for an uncomfortable lunch that’s paid for with a company credit card. In that season’s finale, the paper company uses Hooters to cater its “Casino Night.” And in season three, when Angela describes Hooters as a strip club, Michael counters with the argument that Hooters is a family restaurant with 400 locations worldwide.

According to the company website, Hooters has more than 450 locations in 44 states and 29 countries.

The program: “M*A*S*H*”

The plug: In the third season of the Korean War-based sitcom, a party is held at the 4077th to honor wounded Greek soldiers. Company clerk Radar O’Reilly rescues the feast’s main course — a lamb — by giving the animal an army medical discharge then arranging transport for the lamb to reach Radar’s home in Iowa. To keep their Greek guests happy, Hawkeye and Trapper devise and shape a new meal out of a famous meat popular in the U.S. military. They build a SPAM lamb.

More than 36 year after that episode, Hormel’s SPAM is alive and kicking, having sold more than 7 billion cans of the processed and pre-shaped slabs of chopped pork shoulder and ham.

The program: “Ally McBeal”

The plug: Office assistant Elaine Vassal dreams up a new invention to help women prevent wrinkles: “the face bra.” During an episode of the late-1990s, iconic program, the odd contraption became big seller with women.

In Clearwater, Fla., Vicki Southard has created the real deal — a “non-surgical face lift” that she initially nicknamed “the Face Bra” based on that Ally McBeal bit. Today, she markets it as “the Face Wrap.”

“People mix the shows and episodes up – especially during media interviews, hosts and anchors have commented that it was from a ‘Seinfeld’ show,” Southard lamented. “We used that nickname for awhile. As it turns out, the ‘Face Bra’ isn't a great name anyway. Women don't particularly like wearing bras and the thought of wearing a bra on the face isn't very desirable. Our product is like a body wrap, but it's for the face, hence, The Face Wrap.”

The program: “30 Rock”

The plug: The writers for this comedy about an imaginary TV comedy took on the issue of product placement with a harsh slash of irony. Character Liz Lemon, who plays the creator of the series, argues against “compromising the integrity of the show” by using it to hawk products.

One beat later, a producer named Pete holds up a bottle and proclaims, “Wow, this is Diet Snapple?”

“I know,” Liz responds,” it tastes just like regular Snapple, doesn’t it?”

More characters then weigh in on the wonders of Snapple, including Liz’s personal assistant Cerie, who announces: “I only date guys who drink Snapple.”
