Prov. Very intelligent people tend to come up with the same ideas at the same time. (Used playfully, to commend someone for expressing the same thing you were thinking of; implies that you are congratulating that person for being as smart as you are. Also Great minds run in the same gutters, a casual and jocular variant.) Jill: Let's ride our bikes to the store instead of walking. Jane: I was just thinking we should do that, too. Jill: Great minds think alike.
