Burns and Allen frequently used running gags as publicity stunts.
During 1932–33, they pulled off one of the most successful in the business: a year-long search for Allen's supposedly missing brother.
They would make unannounced cameo appearances on other shows, asking if anyone had seen Allen's brother.
Gracie Allen's real-life brother was apparently the only person who did not find the gag funny, and he eventually asked them to stop. (
He dropped out of sight for a few weeks, at the height of the publicity.)

In 1940, the team launched a similar stunt when Allen announced she was running for President of the United States on the Surprise Party ticket.
Burns and Allen did a cross-country whistlestop campaign tour on a private train, performing their live radio show in different cities.
In one of her campaign speeches, Gracie said, "I don't know much about the Lend-Lease Bill, but if we owe it we should pay it."
Another typical Gracie-ism on the campaign trail went like this: "Everybody knows a woman is better than a man when it comes to introducing bills into the house."
The Surprise Party mascot was the kangaroo; the motto was "It's in the bag."
As part of the gag, Allen (in reality, the Burns and Allen writers) published a book, Gracie Allen for President, which included photographs from their nationwide campaign tour and the Surprise Party convention.
Allen received an endorsement from Harvard University.

Allen was also the subject of one of S. S. Van Dine's Philo Vance mystery novels, The Gracie Allen Murder Case.
Typically, she could not resist a classic Gracie Allen review: "S.S. Van Dine is silly to spend six months writing a novel when you can buy one for two dollars and ninety five cents."

Another publicity stunt had her playing a piano concerto at the Hollywood Bowl (and later at Carnegie Hall).
The Burns and Allen staff hired a composer to write the Concerto for Index Finger, a joke piece that had the orchestra playing madly, only to pause while Allen played a one-finger scale, with a final incorrect note.

The orchestra would then play a musical piece that developed around the "wrong" note.
On her final "solo", Allen would finally hit the right note, causing the entire orchestra to applaud.
In fact, the actual index-finger playing was done off-stage by a professional pianist.
The concerto was featured in the film Two Girls and a Sailor (1944), with orchestra conducted by Albert Coates.
