- In the Roger Miller episode of The Muppet Show, the theater is swept with an epidemic of "Cluckitus", a disease that causes anyone infected to turn into a chicken. Kermit, worried that the news of this affliction may upset the guest star, orders that the epidemic be kept secret (an impossible feat, as Muppets-turned-chickens retain their normal voices). This leads to a specific denial from Robin:
Robin: We aren't turning into chickens!
- Robin's denial became even more suspicious just a minute later, when he caught it.
- The National Anthem of Troller's Gill in Roger and the Rottentrolls (which also plays as the end credits roll) alleges that Rottentrolls are 'not at all totally, utterly stark-raving mad!'
