How I Met Your Mother gave us a little break from the dramatic love triangles and emotional baby blues with "Ring Up," a lighthearted episode that didn’t do much for the seasonal story arc, but managed to hold its own.
Wearing her newly re-sized heirloom engagement ring, Robin realized for the first time what it was like to feel invisible. This wasn’t Robin’s first engagement, so I’m not sure if Robin experienced the same phenomenon while she was engaged to Kevin, (maybe Kevin’s engagement ring just wasn’t as effective as Barney’s ring at making her off limits? I mean I can’t even remember Kevin’s ring.) Nevertheless, I got a good chuckle out of Robin’s musical portrayal of her life before the ring and of her experiences after putting on the ring. The LOTR/Hobbit references and Robin’s sudden invisibility when putting on the ring were simple, silly gags, but they got me every time.
