Oh, Mark, you never learn, do you?

You know what's worse than heartbreak? Getting spoilers about a movie that you were so eagerly looking forward to. That shit hurts, and if it's a movie like 'Avengers', then that's the worst thing in the world, don't even fight me on that. 

But, looks like Mark Ruffalo is a sadist who likes to watch people suffer, or maybe he's just a little confused and doesn't know when to shut up.

We all know Mark and Tom Holland's long history of accidentally spoiling so many Marvel movies, but Mark one-upped Tom by literally spoiling 'Thor: Ragnarok' by being on Instagram Live during its premiere. Oh, Mark. (yes, this will be a phrase that's repeated throughout)

And how can we forget the time, when during an interview, Mark said this about 'Avengers: Infinity War' - “Wait till you see the next one, everybody dies.” Oh, Mark.

Don Cheadle's face says it all.

The best thing about Mark, though, is that he at least he tries to cover up his mistakes and that's what he tried to this time as well. 

But, since he doesn't think before speaking about multimillion-dollar movies, he obviously doesn't think before tweeting about it as well.

.@JimmyFallon, I trust that you will cut my spoiler slip on the show tonight. That was “off the record” homey. Please don't get me in trouble with Marvel (Barry) again. DM me back. M

Yes, tweeting about your goof-up for the world to see, especially the people who can fire you. Oh, Mark.

Apparently, this is the clip in question.

I LOVE YOU @MarkRuffalo WITH OR WITHOUT SPOILERS #FallonTonight pic.twitter.com/ZSkPJfdp2v

Jimmy Fallon also decided to keep the joke going and replied with this.

Dude, it's too late - already sent the final show to Burbank for air. Are you sure you're gonna be in trouble? We could maybe bleep it out. What is “DM”? https://t.co/GMds1hGO8X

But, it was too late. The Russo brothers got to know about it before Mark could fix it, and well, now you know the reason if The Hulk does not show up in the next Avengers movie.

Mark, you're fired.

I have one question –

(Don't come at me with 'it's a joke', I know that already, thank you)

Oh, Mark.

Guys... can we talk about this? https://t.co/PYe56UiUgO

Now, I just can't wait for Mark Ruffalo to accidentally reveal the title of the movie. Do it already, man, we're all waiting, we know you want to!
