Valentine's Day is fast approaching and Spider-Man has no idea what to get Mary Jane. Each year she upstages him and he feels like a chump, but this year will be different. He spends the week reflecting on Mary Jane, particularly recalling a night when he showed her how to use his webshooters and when he told her how he pranked Johnny Storm with a web-bat with them. Eventually, after fighting Dragon Man with the Avengers, he realizes exactly what to get her.
Valentine's Day evening, Peter takes Mary Jane into the garden and presents her with two bracelets and a pair of thumbnail plates. When she touches the plates, webbing fires out of the bracelets. In other words, they're modifed webshooter bracelets. Later that night, the two travel to a building outside where Johnny Storm is picking up his car and pull the prank from earlier all over again.
