That's what you get for giving up on Ellen, Jon. Thank God he's not giving up on that automatic-wrinkling shirt, which is very funny comics shorthand.
Yes Garfield, Wendy is "clever." Her wordplay turnabout on old Jonny, however, required a convoluted setup in which Jon more or less handed Wendy the punchline on a platter. Because really, who besides Jon would compare his adorability to a non-specific animal, but get specific enough to say "small woodland creature"? When the comeback requires such an unnatural come-on, your wit is less Mad Magazine's "Snappy Answers to Stupid Questions" and more Cracked Magazine "Shut-Ups."
