Amy Schumer has made a name for herself over the past couple of years as being a pretty original badass comedian.
However, many people are now suggesting that she stole several jokes from the late Patrice O'Neal, as well as from Wendy Liebman, Tammy Pescatelli, and Kathleen Madigan.
Over the weekend, Liebman, Pescatelli, and Madigan had a now deleted Twitter conversation about her that was sparked by this tweet.
Fellow comedian Chuck Martin then implied that Madigan had had similar experiences.
At this point Pescatelli joined in, claiming Schumer had "stolen" the work of female comedians.
Pescatelli then linked to a joke she made during Comedy Central's Half Hour in 2006.
She then compared it with a joke from the trailer of Schumer's movie Trainwreck.
Then Pescatelli linked to a joke Madigan made during a sketch called "Slap Oprah", back in 2011.
Before comparing it with a sketch Schumer did in 2014 called "Slap Chef".
Pescatelli went on to tweet: "So many more but nobody listens...at least Cosby knocked his victimes out b4 he raped them."
She continued: "No beef. Just presenting facts of oppression and degradation. I tell my truth today, because I too, have a dream."
But before long, people across the internet were drawing more comparisons between Schumer's jokes and the work of other comedians.
People pointed out that following her joke about slapping food out of Oprah's hands, Madigan goes on to say Oprah could also pay somebody to move her limbs and exercise for her.
While after her "Slap Chef" sketch, Schumer jokes about the "Sleep Gym", where you're induced into a coma before trainers work your body for you.
Then there's this joke, made by Liebman in the 1990s, about making men pay on a first date.
And in 2015, Schumer made a similar joke.
Other people pointed to Patrice O'Neal's stand-up from 2006, in which he jokes about sex moves.
Before pointing to Schumer's stand-up from 2015, in which she makes a joke on a similar theme.
The next joke O'Neal makes is this one.
While Amy says this.
It wasn't long before people began calling Schumer out on Twitter.
Others pointed out that she used to open for O'Neal and may have heard his material then.
However, now Schumer has denied any allegations of stealing jokes.
She also appeared on a US radio show, The Jim Norton Advice Show, to "clear her name".
Schumer went on to say that she believed Pescatelli was deliberately trying to stir up trouble with her tweets.
She said: "Kathleen and Wendy know me and don't believe I would do that – I think that Tammy is trying to get something going, I don't know ... I think she is upset ... people get upset by success."
However, after Schumer's comments were reported, Pescatelli took to Twitter to reject claims that she was starting trouble deliberately.
Many people have spoken out in support of Schumer, including actor and comedian Aziz Ansari.
When asked for further comment, Schumer's publicist referred BuzzFeed to her interview with The Jim Norton Advice Show.
