When it's your co-worker's birthday, you could write "Happy birthday" on their Facebook wall, but that's so boring. Everybody does that. It's much more fun to hilariously troll them. For example, you could scratch "HAPPY BDAY" on their car with your keys. Wait, sorry, that's not trolling. That's just vandalism. But if you can come up with a funny way to troll them that doesn't involve breaking the law, they'll probably appreciate it.

Believe or not, it's Chris Pratt's 39th birthday. The actor's had quite a metamorphosis, going from the funny chubby guy on Parks and Recreation to the funny physically fit guy in Guardians of the Galaxy. Also, he's one of the four sexy Chrises who nobody can tell apart. The others are Chris Pine (aka Steve Trevor), Chris Hemsworth (aka Thor) and Chris Evans (aka Captain America).

Chris Pratt and Chris Evans are both in the Marvel Cinematic Universe, but their characters, Captain America and Star-Lord, have never shared a scene together. No, not even in the biggest crossover event in history, The Avengers: Infinity War. The characters were on separate journeys, and both fought Thanos at different times.

But despite their lack of interaction in the movies, the actors have good rapport. On Twitter, Chris Evans wished Chris Pratt a happy birthday, while hilariously trolling him. Evans shared a photo of his dog peeing on a fire hydrant with a Star-Lord mask plastered on top. A sign on the post behind it read, "Property of Star-Lord. Dogs beware!" In the caption, Chris wrote, Happy birthday @prattprattpratt from me and this giver of zero f*cks. We hope you’re getting showered with affection today."

Whoa, I didn't expect Captain America to be so good at Twitter after being frozen for 70 years. Also, it's surprising to hear him use dirty language. The man's really changed since he became a war criminal. (We should have suspected he'd turn evil once he grew that glorious Ned Flanders mustache.)

Well, Star-Lord's never one to back down from a battle. He might interfere with a battle and totally screw everything up, like in Avengers: Infinity War, when he punched Thanos in the face instead of helping his fellow Avengers steal the Infinity Gauntlet, resulting in the death of half of everyone in the universe. But he won't back down!

Pratt jokingly replied, "You’ll be hearing from my lawyer."

Well, Chris Evan's birthday is on June 13, so Pratt has about a year to figure out how to troll him back. And considering how much chemistry they have on Twitter, hopefully these two actors get some scenes together in The Avengers 4. Reportedly that film will be the last Avengers movie with the current cast, retiring some characters from the "old guard." (Ironman, Thor, Captain America, etc). Before it all ends, we need to see Captain America and Star-Lord interact. Until then, keep showering us with golden content on Twitter.
