Favre once attempted to trademark the phrase “Black Friday.” Other unsuccessful trademark attempts include the phrases “Relentless egomaniac,” “You’re a chimp, chump, not a champ,” “Favre fever vaccine,” and “That’s what she said.” He also filed a trademark application for “that sign where there’s the letter D and a fence. Like a picket fence. You know what I mean.”
Following the conclusion of Favre’s disastrous season with the NY Jets, he tried to trademark the number 4. He’s still waiting for the results.
