Parodies and Appearances (WWTBAM/U.S. version)

The success of Who Wants to Be a Millionaire? (U.S. version) has provided plenty of opportunities for various shows and movies to parodies or have their characters make appearances on Millionaire as a (sub)plot.

Ace Attorney Investigations
In this video game from 2009 by Capcom, while being interrogated by protagonist Miles Edgeworth, the smuggling ring leader establishes an alibi by stating that he was watching a play at the king of a killing. Upon noticing a contradiction in their statements, Edgeworth states "The special move today [as part of the play] was the 'Early Summer Rain Jab', Is That Your Final Answer?', in reference to the shows' catchphrase.

The Amanda Show
The recurring skit of the show was called ''So You Wanna Win Five Dollars" hosted by Tina (Amanda Bynes) the contestant (usually a character from another recurring skit on the show) who isn't very bright, has to answer three questions along with the final question being only worth $5.00.

The Assistant
In the episode "Welcome to the Assistant, Now Go Home", had a spoof a Millionaire as Who Wants to be Andy's Assistant? (mostly referring to Andy Dick).

The Big Cartoonie Show
This Kids WB show had its own spoof called Who Wants to be a Millooneyaire?.

Cartoon Network
In this commercial for The Powerpuff Girls, Mojo Jojo is sitting in the Hot Seat when he is trying to answer a question. He decides to call someone with Phone a Friend. The Powerpuff Girls are sitting back at home  watching Mojo as Blossom says "Jeez Luis! Can You Believe This Guy?" The Buttercup says "About Time Already, for Cryin' Out Loud!" former host Regis Philbin made an off-camera appearance.

Friends of the People
This was spoofed as a "million-dollar game show heist" host of Cash Cab Ben Bailey briefly makes an on-camera appearance.

Let's Make a Deal (Brady)
This had a recurring mini-game called Who Wants to Answer Multiple-Choice Questions for Cash and Prizes? where contestants have to answer three general knowledge multiple choice questions for cash. Each question contained three answers. When contestants were to confirm their responses, Brady would ask "Is that your definitive response?" (similar to "Is that your final answer?" on Millionaire) Each correct response was worth $500. However, choosing a wrong answer at any time automatically ended the question round. Afterwards, contestants could risk the cash on one of two curtains in hopes of winning a bigger prize (usually a car).

The Lion King 1 1/2
In the DVD, theirs a special featured game called Who Wants to Be King of the Jungle? while the format is very similar to the regular gameplay of Millionaire, the questions are shortened to ten instead of fifteen. There are two lifelines that are different in this version as well. The 50/50 lifeline stays the same. The two different lifelines are "Poll the Herd" (Ask the Audience) and "Phone an Animal" (Phone a Friend). The viewer plays as Timon trying to help him be "King of the Jungle". Also Timon plays for grub not cash. Former host Meredith Vieira does make an appearance as host in this special feature. The questions are Lion King related. Pumba also makes an appearance. One of the Phone an Animal (Phone a Friend) choices is Pumba (despite Meredith saying you can call any animal if you're stuck on a question) as you win food (in the case "grubs") instead of cash.

MAD TV
The original one spoofed as a "Celebrity Edition" then as "Who Wants to be President?" as then as a "Lorraine" skit on the show.

Pookie Poo
The internet cartoon of the late 90's had a spoof of Millionaire where the self-titled main character appears on the show.
