“Psych” is cordinally inviting you to the wedding of Carlton Lassiter and Marlowe Viccellio in “Deez Nups,” one of the best episodes of Season 7, if you ask us. Check out this sneak peek clip and get excited for the pending nuptials.

But, of course, every wedding needs a good bachelor and bachelorette party the night before. Shawn and Gus are on the case for Lassiter, kidnapping him onto a party bus — driven by Henry, natch — and also including Woody and Lassie’s friend Stumpy. Shenanigans are imminent.

There is also a bachelorette party that Juliet and the Chief get roped into attending and hilarity ensues. “Psych’s” wedding airs Wednesday (April 10) at 10 p.m. ET/PT on USA.
