Strips

@Helmeet: Yes, and when I look at Wally's contributions and those of Lady Liberty, and then compare them to yours, I know why. Beginning, in Wally's case, with the proper use of indefinite articles.

And that, ladies and gentlemen, is why you prefer an useless Wally. That and the Stump of Liberty, of course.

I have a feeling it was not coffee at all, but "sewage" remaining after Dilbert treated it in his machine and made potable water from it. That is why Wally is not taking a sip or bringing it anywhere near his mouth.
