I already know that life is deep, but I still dig her
Wayne draws a double-pun here, in both instances using life as a woman (“life’s a bitch…)
In the first sense he means that though life is deep (complicated, difficult), he still likes her.
In the second sense, he says that though life is deep (long-pussied), he can still fuck her out. He used a very similar line in “Megaman”.
