 Ted is searching for a date for a wedding. He asks Robin to come with him to the wedding as his "date" and she says yes. Problems evolve when the bride-to-be Claudia tells him he didn t check "plus one" on the reply card and forbids him to bring someone along to the wedding. Ted now has problems to tell Robin that she cannot come with him and asks the Stu, Claudia s future husband, if he can bring a "date" and he says "yes". This leads to further problems.
