While reading the Garfield comic strips on the Garfield site done over the course of the nearly 40 years the strip has run, I noticed this strip (for October 30, 1980) poking fun at a Swiss Army knife.
In my opinion, useless?! Seriously, whoever drew the strip must not do much. I've had one for ten years and done everything with it. And I've never seen umbrellas on any, other than the etch on the blade of Wengers and older Victorinoxes.
