Yes, it's Repeater Ranger, reception renegade, the cellular superhero! Yes, Repeater Ranger will help you get cell phone reception wherever you are, because he can fly, hover, and he wears a cellular repeater on this chest. And so whenever he spies someone who can't get any bars, he'll show up to save the day!
Yes, you can now make that call from the bottom of a long underwater tunnel, on the top of some remote mountain, and even when you're down in a diving bell, because Repeater Ranger has the most powerful cell phone repeater ever constructed: it's got super powers like him! Plus, Repeater Ranger has all the same powers as Superman, but he doesn't really enjoy fighting crime, and he's pretty much ambivalent about justice and stuff like that, but he's obsessed with cell-phone reception, because when he was a child, growing up in Montana (having arrived there from another planet as a baby) during the very beginning of widespread public cell phone use, the girl he loved demanded he call her every day, but he could never get any bars on his phone, so he could never call her, and she dumped him (!). And so now he fights for cell phone reception wherever it's the weakest, righting wrongs and, um; well, actually he doesn't really right wrongs, as I said before. But if you need a strong signal to make a call and you have "no service", Repeater Ranger's on the case!
Oh, but his super-heroism is not always easy, because his nemesis, the super villain The Lethal Landline is always trying to kill cell phone reception to force people back to using landline phones! Can Repeater Ranger save the day and get us full bars, or will The Lethal Landline drop his call for good? Tune in for the next exciting episode of: Repeater Ranger: Cell Phone Superhero!
(This might make a fun TV ad campaign for a cell phone company claiming to have the best nationwide service. They could show this scenario, and then claim you don't need to rely on such a superhero to save the day when you get {whatever company's [AT&T, Verizon]} service.)
