Toys R Us is saying goodbye. The toy retailer is ending its run on Friday, June 29, closing all stores and wrapping up its going-out-of-business sales. That day marks the true end of the retailer's presence in the United States. On Friday, the retailer posted one final goodbye message on its website, which hasn't been active since it stopped accepting online orders in March. Here's the message: Thanks to each of you who shared your amazing journey to (and through) parenthood with us, and to every grandparent, aunt, uncle, brother, and sister who's built a couch-cushion rocket ship, made up a hero adventure, or invented something gooey. Promise us just this one thing: Don't ever grow up. Play on! The second-to-last line, "Don't ever grow up," is a riff on Toys R Us' famous jingle: "I don't want to grow up, I'm a Toys R Us kid." From June 29 forward, there will be no more Toys R Us kids, sadly.
