"Comedian Ed Gamble's Tube Poster Controversy: Hot Dog vs. Cucumber"

Comedian Ed Gamble was asked to change a London Underground poster for his standup show, "Hot Diggity Dog," featuring a hot dog due to the transit network's ban on junk food advertising. Gamble, who is diabetic and co-hosts a food podcast, replaced the hot dog with a cucumber to comply with the policy. The ban on ads for high-fat, high-sugar, and high-salt foods has also affected other advertisements, sparking controversy and criticism from the tabloid press.
