I had a lot of problems with this episode but the one that bothered me the most was the nanny part. So, this guy, whose job is to watch the baby, who I'm assuming will need to be watched on the day that a wedding is going on, is leaving town. Not for a family emergency, which I can understand, but to visit his girlfriend. And he's leaving on the day of the wedding, just when people need to start getting ready, and therefore the baby needs a caretaker. In what world does that make sense? That's a bit like letting your personal chef go on vacation on the day that you are having a sit down dinner for 50 people. It bugged me. Why they felt they had to squeeze in all these story lines is beyond me.
However, I did love Lily dropping the rose pedal, picking it up, etc. That was funny.
