make odd bedfellows

Of a pair of people, things, or groups, to be connected in a certain situation or activity but to be extremely different in overall characteristics, opinions, ideologies, lifestyles, behaviors, etc. A notorious playboy musician and a buttoned-up media pundit may make odd bedfellows, but the two are coming together this month to bring a spotlight to suicide awareness. I thought that the two writers would make odd bedfellows for this class, given the drastically different nature of their writing, but their books actually have a lot of parallels in terms of themes and constructs.
