Marmaduke swallowed Sarah's wristwatch and he's sick to his stomach. Marmaduke's owner-girl makes a watch-related pun so asinine it takes at least three months off of my life every time I read it.

(side note-- I initially didn't notice the pun and thought Owner-Girl was actually saying "sick." Such is Marmaduke's patented brand of "phantom humor" that today's strip would have been no more or no less funny than any other had that been the case)
