Happily Unmarried

S1 E1: Shannon Tweed hates surprises.  Gene Simmons loves them.  On his way out of town to attend the grand opening of the Hooters Hotel & Casino in Las Vegas, he asks Nick and Tracy Tweed (Shannon's sister) to plan a surprise birthday party for Shannon on his behalf.  While in Vegas, he gets roped into attending the wedding of a fan and his fiancée -- and even gives the bride away.  When Shannon inadvertently finds out that Gene was not only planning a surprise party for her AND that he attended someone else's wedding, she ups the ante and plans sweet revenge on her longtime boyfriend.
