When Fox's My Big Fat Obnoxious Fiancé draws to a close, bride-to-be Randi Coy will learn that, while she was fooling her family into thinking she'd really marry a tubby tool, the reality show's producers were tricking her into believing that her intended was just another contestant. (In fact, he's an actor.) But that doesn't mean the Coy clan wasn't still hoppin' mad over the deception. Have you seen the promos? In future episodes (airing Mondays at 9 pm/ET), those poor people get put through hell!

"I don't think [what we did to them] was necessarily cruel," the funny girl insists. "[The prank] was going to end; that was my [justification to go ahead with it]. It was two weeks. I didn't look at it as harming my family. I thought it was going to be all fun, but real emotions did play into it. It got tricky. I got some reactions that I didn't anticipate."

Gee, imagine: Coy's nearest and dearest didn't do a happy dance upon learning that she'd be tying the knot with a troglodyte. Color us astonished. Nonetheless, she says that she and her "fun-loving" relatives are still on speaking terms. "We're very close. Hopefully, in the end, we'll be OK. They're pretty resilient. But this was quite a whirlwind we went through." Even she isn't sure she's wrapped her head around the big twist yet. "I'm just digesting it all, and I'm not going to lie — it's hard. I thought I was doing the ultimate practical joke, but the joke was on me." Ha. And they say karma has no sense of humor.
