And yet most people remember his acts fondly, and major acts sing songs and make award-winning movies about him. Though it probably galls his ghost that most people remember him mainly for his ethnic humor about Eastern Europeans (as both “Foreign Man” and Latka). Though admittedly it was by far his funniest material.

Andy Kaufman’s ‘‘Tony Clifton’’ routines were built around little more than audience discomfort  
Kaufman was ruthlessly unfunny. Nothing in his entire career was the least bit amusing; he tried super hard to reach the level of “so weird it’s funny” but never even got close, and the only reason he ever had a career in the first place was because edgy standup in the 1970s was an extended naked emperor metaphor.

Not to mention that “awkward” taken to an extreme is funny in and of itself. Andy Kaufman’s “Tony Clifton” routines were built around little more than audience discomfort. Plus the audience reactions in this case were to die for. Berry Punch’s expression, and then Lyra and Bonbon, that was even funnier than the jokes themselves. And the specific examples, “Walking around, and picking up things with our teeth.” It’s canonical to the show that earth ponies are better at growing crops, and tend to be stronger and with more stamina; it’s not however canonical that earth ponies actually realize that. Yet they are basically the core of Equestria. So the sheer absurdity of Maud’s examples is so wonderfully ironic. And then there’s the aspect of parody. There are human-world jokes like this. They are among the most beloved jokes ever. The best-selling book series of all time is Truly Tasteless Jokes, which just laid out chapter after chapter of jokes about every subgroup of people big enough to have jokes about them in the English language. But they go over like lead balloons today in public, because everyone’s so worried about whether someone in the audience might be offended. Since in this case there is literally nobody in the actual audience who’s an earth pony, they were free to parody the tone-deaf comedian and the stunned audience reaction.
 
The only thing funnier in this episode was Limestone’s reaction to finding out Maud had a boyfriend.

@TexasUberAlles  
Maud was being too meta for her audience. Her jokes were funny, but only if you remember all the fandom debate about “Earth ponies are useless because they have no magic”.

Earth Pone is best pone.

In-universe, Maud should really stay away from race comedy.
 
Onscreen… this scene was bad. All of Maud’s standup routines so far have been genuinely funny along the lines of Stephen Wright, where her deadpan delivery and rock-solid sense of timing make the audience’s expectations part of the joke, but this was just “Maud says some awkward unfunny things, The End”.

Oh brother, THIS PONY STINKS!!!  
 
(This fish’s words, not mine!)

Personally I think that earth ponies should use more your strength or have abilities connected with the earth such as sensing earthquakes, other things related to the earth, etc.

@Otterhand  
Funny enough that her boyfriend is literally a “Mud” horse.

@Ferrotter  
Lyra: “It’s totally okay for me to say Mu…”  
Bon Bon: “LYRA!!!”

…I thought that was kinda funny.

@Charlemage  
Pretty much everypony except Lyra, and she’s married to an earth pony.

“GET OFF THE STAGE MUD HORSE!!!”  
Maud:“Hey! that is racist.”  
“…I’m sorry…”

@PonyPon  
Yep.

@AlexAngel  
Mr.Cake seems to do it fine and without complaining

Good luck changing diapers on your foals with your teeth.

@Sweet Blast  
To herself?
 
And 99% of the audience?

Sorry Maud. You are only effective when Discord is on stage. That one was. Racist. A little bit.

Notice that most ponies watching are earth ponies.

Earth ponies suck

So what’s the deeeeeealllll with earth pony ?
