Ok, it's not as good as my ring, but the Amazing Fish Pen is just about the best non-fake commercial I have ever seen. David and I are watching Coupling on BBC-A, so we are already laughing, and the The Amazing Fish Pen is a main sponsor. So I found it on YouTube.
Made from "super strong alloy"
"It looks like an ordinary pen, but watch it instantly transform into a durable fishing rod."
"Casting's not a problem with the fish pen."
