Danny Trejo is an actor known for his work in From Dusk Till Dawn, the Spy Kids films and the Machete series.
Danny provides assorted voices for Family Guy, including appearing as himself in a cutaway gag in "Dog Bites Bear" when Meg notes that Peter and Lois have a weird but strong relationship, like Danny. Later, the voiceover from Vin Diesel on Stewie's The Fast and the Furious DVD set notes that a friend that kills another friend is not strong and Danny Trejo is strong.
