Oh, no!  I’ve reduced myself to potty humor.

It seems like it should work.  You pull off the 4 panels, read them then use it.  Heaven forbid you get out of sync.  Pull off the last three panels of one comic and the first of the next and you’ll be sitting there saying, “I don’t get it.”  But, then, you might be saying that even if you do pull them off of the same comic.
