Marmaduke's owner-man, is taking Marmaduke out for a walk. Owner-Man asks Marmaduke to slow down, implying that their walk is a competition rather than exercise. Marmaduke invites Owner-Man (who appears to be suffering from mild cerebral palsy) to kiss his ass.

Marmaduke is fetching the paper for his owner-man. Marmaduke's concept of "fetching" is limited primarily to the act of getting something and chewing on it; fulfilling his owner-man's wishes is not really part of the process.
