Cell Phone Valentine's Day Ad (Proposed)

I don't know if this has been done before (probably, as it's pretty obvious, but I haven't seen it before), but I think a fun Valentine's Day ad (or just a regular ad) for a cell phone plan would be to show two teenagers on their cell phones, on split screen, and they're saying, back and forth: "You hang up first." "No, you hang up first." "No, you hang up first." "No, you hang up first." and the announcer chimes in, saying: "With the new (whatever) plan, you can take all the time you want, because you've got all the time in the world, for one low price."
