Modern Family had a few standout episodes in its first season, but the majority of them were good for a few laughs and really nothing else; this felt like one of those season one episodes. The Claire and Haley were ever so boring and find it funny that a show called Modern Family could be so cliched.
Speaking of cliched, Lily shooting a commercial? That's never been done on a sitcom before. At least make it funny if you are going to rehash something done to death like the kid going on a commercial.
I think they should change the name of this show to Cliched Family.
