Marmaduke

"Aren't you supposed to be holding the ladder?" asks Phil.
He and Marmaduke are both on the roof somehow. He seems to be addressing Marmaduke, suggesting that he entrusted his safety to a large but uncomprehending dog, and even though Phil is closest to the ladder, it seems that Marmaduke has somehow managed to get up past him without him noticing. How did Marmaduke even climb a ladder anyway? This comic raises more questions than it answers.
