Here's a great digital marketing wheeze. Puma asked fans to tweet their favourite Puma-wearing player to get a personalised "autograph".
Amy, Mundo, Ayzah, and many more were delighted with these "personalised" notes from Manchester City and Argentina striker Sergio Aguero.
All you had to do was tweet @puma and a player, with the hashtag #fastergraph, and you'd get your own message. WHAT COULD POSSIBLY GO WRONG?
