I AM GROOT.
(The GrootBoard Android app will replace your virtual keyboard with something better: the ability to vehemently declare that you are, in fact, the incredibly loveable tree-alien from Guardians of the Galaxy. It costs $0.99 on the Google Play Store, but will be invaluable in future interactions with other Groot lovers.)
