hi there. you have no clue what you speak of.
ali g is a character of sasha's that makes fun of white fubu wearing mindless wiggers, but at the same time he also gives props to hip hop. if you have watched any ali g you'd know that sasha's character, as well as himself, love pac's music. the joke is not that tupac is the name of his dog. the joke is that the dog is licking his nuts.
people just reach to create beef. pretty stupid if you ask me.
