She opened her own shingle

A couple were talking about a law school grad who could not get a job with a big firm. The wife said, “she opened her own shingle.” This is a congruent conflation of “hang out (one’s) shingle” and “open (one’s) business”, both meaning to open an offfice for one’s practice. Or maybe the grad became a roofer? A big thank you to David Barnes for hearing this one (at the “Friday evening glass of wine” time) and sending it in.
