Required: intimate knowledge of dorm room furniture.

I've always liked this strip for its simplicity and sheer selfishness on Nick's part. Hey, I have a bed, you have a bed, but neither of us has a Universal-type weightlifting apparatus. Why don't you surrender your bed so I can have just that? In retrospect, I'm not sure the phrasing of the last panel--or the drawing--brings the gag full circle. A cursory reader might assume Nick constructed the machine out of only bike parts, even though the mattress is clearly visible. Do I overthink? Lastly, what the heck kind of machine is that anyway? Some kind of horrific forearm/quad combo? Count me out.
