The clip from social media was seriously funny and quickly went viral across Twitter!
Haskell then got revenge on his former international colleague by heading to the bookstore himself and putting stickers on Marler's book.
However, Marler has quickly responded as only he would as their autobiography war rages on.
The brilliant nicknames Joe Marler has given teammates in his autobiography
1. Joe Launchbury (Slosh, Sloshbucket, or Biscuit)
"He has the biggest arse in world rugby - and was forever knocking things over."
2. James Haskell (The Unflushable Turd, Rig City)
"Despite being embroiled in a number of off-the-pitch controversies over the years and falling foul of various regimes, the unflushable turd has repeatedly bounced back."
3. George Kruis (Shnooze or Shnoz)
"Because his chat is so boring it will make you fall asleep"
4. Mark Lambert (Smug Pig)
"Not only did he act like he was all superior, he had a reputation for really, really enjoying his food."
5. Dan Cole (Colar Bear)
"He looks like a polar bear, an animal renowned for being miserable."
6. Mako Vunipola (Snorlax)
"The name has nothing to do with snoring. Mako sleeps for what seems like 22 hours a day."
7. Willi Heinz (Beans or 57)
"I'd call him Beans if his surname was Jones because he's got a beaned shape head."
8. Matt Cairns (The Bollock)
"Another simple one. He has a shiny bald head that look like a shiny, bald, bollock."
