I forgot to watch last night's but I thought the previous one was fucking hilarious. It's best when Wilfred just breaks out doing random dog type stuff mid sentence or just randomly out of nowhere.
Also lol @ him trying to poison Ryan with theobromine which is the chemical in chocolate that is poisonous to dogs. Then when the doctor tells Ryan what it is Wilfred was like "tell him I put raisins in there too" which are also poisonous to them as well.
