F-Mail, was a fictitious electronic messaging service from the YouTube comedy series The Lenny Lego Show. It served as a running-gag.
F-Mail was first introduced in Mr. Fireman spin-off film. In the film, "Mr. Fireman", sets up an F-Mail account for Buzz Tarco late at night when he's asleep, as to make up for various acts of pain regarding Buzz's life, such as ruining a newspaper photograph. When Buzz Tarco wakes up, he finds that hundreds of junk-mail letters are flooding into his inbox. Eventually it causes his laptop to completely crash. When Buzz calls computer maintenance to repair it, he learns that it will take a minimum of a week and a half to fix. As a result of going a week and a half without a computer, Buzz Tarco is thrown out of his online college.
F-Mail returns in The Lenny Lego Movie 3, in-which we find that the film's main villain, Clonebot, as well as Mr. Fireman, both have an F-Mail account. Mr. Fireman sends Clonebot a humiliating video of one of his henchmen Scott Diggerman, being taunted on camera having been captured by Mr. Fireman during a failed attempt to re-kidnap him.
F-Mail has also been seen in a few various Lenny Lego episodes.
F-Mail will return for the updated series "The Lenny Leggo Show", playing relatively the same role.
