We love awkward celebrity endorsements as much as the next guy, but this one might just take the cake. An email sent out by Microsoft to an anonymous focus group recently hinted at the possibility of Johnny Knoxville joining the ranks for a publicity campaign. Knoxville appears set to star in a series of ads aimed at countering the Justin Long-sourced Mac vs. PC ads that have become all but synonymous with Apple’s recent marketing track. Great. Copycat ad campaigns are so fun. On the upside, it looks like we might get to see Knoxville inflicting some physical damage on a comptuer or two, so we won’t judge too savagely just yet.
