Jeremy Renner Just Found An 'Avengers: Endgame' Ad In The Most Hilariously Awkward Place

Marvel Studios fans will finally learn the ultimate fate of some of their favorite characters when Avengers: Endgame hits theaters on April 26.

Anticipation is increasing with new teasers and ad campaigns. Even fan theories are circulating, like the disgusting one about Ant-Man defeating Thanos by becoming a colonoscopy killing machine.

While we're on the subject of potty humor, actor Jeremy Renner shared an interesting placement for an Endgame ad in Europe.

Let's just say Renner's Hawkeye will be keeping a close watch on those who urinate standing up.

The ad is definitely not for the pee shy.

Renner posted the photo from a bathroom stall on Instagram, captioned with:

"So.... I know they do ads 'differently' in Europe... but #euro-peein' #avengersendgame #aintlookin #ipromise #wtf"

Renner, 48, made a splash in the Marvel Cinematic Universe (MCU) films as Clint Barton, a.k.a. Hawkeye, beginning with Thor (2011), The Avengers (2012), Avengers: Age of Ultron (2015) and Captain America: Civil War (2016).

In response to his observation, the entertaining comments flooded his post.

Always keeping an eye out for justice.

Some with performance anxiety issues may not be up to the task at hand.

It's a cultural thing, right?

Hmm, size envy?

Fans missed seeing Renner in Infinity War, but directors Anthony and Joe Russo assured fans there was a reason for his absence.

"We keep saying, 'Patience is a virtue,' we did not forget the twice-nominated Jeremy Renner."

"We just cooked up a story for him that is a little bit of a long play. Not a short play."

Fans' suspicions about Renner's identity swap were confirmed when a new trailer revealed that Hawkeye was now Ronin, an alias used by several characters within the MCU.

His newly adopted moniker is in reference to a Japanese term meaning "masterless samurai," and the lone warrior's weapon of choice is the katana blade, a worthy upgrade from his bow and arrow.

How did he become Ronin? Fans may have their theories, but we'll have to wait until Endgame to find out the details of his transformation.

We can't wait to stream into theaters on April 26.
