Castle Season 5 guest star Kevin Daniels has been tweeting up a storm lately about his experience on the set of ABC's hit crime procedural. Between his super early call times and rambunctious co-stars, we feel like we've been with him every step of the way.

But today, on his final day of filming, he treated us to something a little extra special: not one, but two behind-the-scenes pictures with Castle stars Nathan Fillion, Seamus Dever, and Jon Huertas.

"Last day on the #castle set," he wrote, along with the above image.

Seamus got in on the action in the next photo, which Kevin captioned with "we're a laugh riot." We'd definitely have to agree!
