Throw It In/Advertising

• Farfel the dog, the ventriloquist dummy mascot for Nestlé back in the 1950s and '60s, would end his familiar jingle (N-E-S-T-L-E-S/Nestlé's makes the very best/chaaaw-klit) with a "chomp" sound. This was because Jimmy Nelson -- who performed him -- was nervous during the auditions, causing his sweaty hand to slip off the mouth control. The executives liked this so much they they kept it in ever since, even when Farfel (and his extended family) were revived in the '90s for a Christmas commercial.
• Parodied in a Geico commercial where Foghorn Leghorn is doing narration for a book, only he is doing a very bad job at it. At one point in the shooting, he also adds in something, which he shortly thereafter admits that he added it in. Eventually, it got so bad that Henery Hawk ended up departing from the equipment room with a bat and was audibly implied to have bludgeoned Foghorn Leghorn with it, presumably to beat some sense into him.
