two birds with one stone

From the phrase kill two birds with one stone.

• "They talk about how 'these places' [pornographic bookstores] are gathering spots for homosexuals. The implication is that if you close down 'these places' you get two birds with one stone."
• "On another occasion, when trying to brainstorm things I could do to make myself feel better despite all the pandemic restrictions, Woebot suggested I “try doing something nice for someone in your life,” like make a calming tea for my housemate or check in with a loved one. I poured my mum some chamomile: Two birds, one stone."
