My LEAST favorite commercial on television right now is this one:
I mean seriously! What the hell? Did a bunch of men get in a room together and think: You know what would be a REALLY funny commercial? Let's compare girl parts to crustaceans and in a round about way make girls think their parts are gross and dirty.
OK, I have a problem with this commercial for all of the obvious reasons, but also any good Gyno will tell you that it is these kinds of feminine products that mess with the delicate female balance and causes the issues they are supposedly going to "fix" in the first place.
To me it is the equivalent of making condom commercials that pick on penis size. Dumb dumb dumb.
