I suspect most have already seen the famous episode of the Miss Teen USA South Carolina contestant’s answer to a geography-related question . (By the way, amazing performance by the host holding the microphone. Could you keep a straight face through that?)
This one seems a bit less well known (if you can say that about a clip that’s been watched 4 million times on YouTube):
The host here is much less impressive (note his commentary in general, and pronunciation of a certain country name in particular). The little boy looks adorable though.
There’s more along similar lines, for example this Family Feud episode.
