Reis was considered to be a bit of a jokester among his teammates and in the soccer community. As an April Fools' Day prank in 2004, the Revs' front office announced their newest foreign acquisition, Luis "El Lobo" Fangoso, who eventually turned out to be Matt Reis wearing a shaggy wig and headband. Although the initial joke died down fairly quickly, Reis' antics helped him win over many Revolution fans (to this day, Revs fans occasionally make joking references to Fangoso when discussing possible player transactions). On April 1, 2007, the Revolution announced that they had resigned Fangoso to a 2-year deal.
