Last night, the cast of "Suicide Squad" unveiled their latest and most extreme bonding session together -- getting matching tattoos done by fellow members of their cast!

So far we know Joel Kinnaman, Jai Courtney, and even director David Ater have gotten tattoos of the word "skwad," as seemingly done by Harley Quinn herself, Margot Robbie.

But as tight as the #skwad is, they aren't the first cast to get matching ink with each other. Plenty of other actors from tight-knit TV shows and movies have also gone under the needle together, too. Check out the awesome tattoos some of your favorite casts are rocking together:

"Teen Mom 2"

Back in 2011, Jenelle Evens, Chelsea Houska, Leah Messer and Kailyn Lowry all got matching little heart tattoos to commemorate their time together on the second season "Teen Mom 2." You can see Jenelle's on her wrist here, just under her tomato sauce-stained hands.

"Mad Max: Fury Road"

Earlier this year Courtney Eaton told Vanity Fair that she and the rest of Immortan Joe's wives -- played by Rosie Huntington-Whitely, Zoe Kravitz, Abbey Lee Kershaw, and Riley Keough -- all got matching tattoos of "three little dots and a triangle." It was probably less painful than all the blood-donor information Mad Max had to get done on his own back in the movie, we bet.

"The Lord Of The Rings"

The nine members of the Fellowship -- Elijah Wood, Ian McKellen, Sean Astin, Dominic Monaghan, Billy Boyd, Sean Bean, Viggo Mortensen, Orlando Bloom, and Jonathan Rhys-Davies' stunt double Brett Beattie (Rhys-Davies himself declined) got a tat of the Elvish word for "nine" on different parts of their body to commemorate their time together on the set of the "Lord Of The Rings" trilogy. You can even see Mortensen's tattoo on his shoulder during the film "Eastern Promises," above, because apparently what Russian mobsters really love is J.R. Tolkien.

"Breaking Bad"

Okay, so Aaron Paul and Bryan Cranston didn't get matching tattoos like everyone else on this list did, but they did get their tattoos together on the very last day of filming their hit series "Breaking Bad." Paul, below, got the phrase "No Half Measures” in an elegant script in his arm, and Cranston, above, got an adorable little secret tat of the show's logo on his finger. Then they tried to convince RJ Mitte to get one too, but his mom wouldn't let him.
