A: Mary had a big fight with Tracy yesterday, and it was so chaotic that a policeman was called in to stop them. Why was Mary so angry with her former best friend?

    B: She blames Tracy for stealing her husband. But, it takes two to tango.

    Note: This idiom means if two people are involved in a bad situation, both must be responsible. This expression dates from the 1920s, when the Latin American tango became a very popular dance. Tango literally requires two partners to perform. The phrase was made popular as a result of a 1952 song by Al Hoffman and Dick Manning named “Takes Two to Tango.” Two versions of the song appeared that year, one by Pearl Bailey and the other by Louis Armstrong. The Pearl Bailey version reached the Billboard magazine best seller chart Sept. 19 where it lasted 17 weeks and peaked at No. 7.
