Today’s Dilbert, with an entertaining idiom blend:
A combination of like a foot in a shoe and like hand in glove. Probably not inadvertent, given Dogbert.
On idiom blends, see Ben Zimmer on Language Log, 10/15/08, with an assortment of examples, including the archetype rocket surgeon; a 9/25/11 posting on this blog on dead as a bag of rocks; and a 11/07/12 posting on this blog on toolbook (and other examples).
(If you want to add examples, please look at these postings first, to make sure they aren’t already covered.)
