Wikipedia: She Stoops to Conquer
She Stoops to Conquer is a comedy by the Anglo-Irish author Oliver Goldsmith, first performed in London in 1773. The play is a favourite for study by English literature and theatre classes in the English-speaking world. It is one of the few plays from the 18th century to have retained its appeal and is regularly performed. The play has been adapted into a film several times, including in 1914 and 1923. Initially the play was titled Mistakes of a Night and the events within the play take place in one long night.

Today I bent down, picked up a chestnut and said “She stoops to conker.” There was no audience for this zinger, so I am sharing it with you.

My friend will always ascend a small staircase leading to an apartment building before we get out our horse chestnuts. She stoops to conker.

I went to see a play last night about a very tall woman who entered a horse chestnut contest against much smaller men. It was called “She stoops to conker.” #1PUN
