Every dog has its day

Everyone gets a chance at success or revenge eventually, no matter how unlikely.

From 16th-century England, rooted in Erasmus' 1500 adage 'even a lowly dog has his day,' echoed in Shakespeare's 1600 'Hamlet' as 'the cat will mew, and dog will have his day. ' It ties to medieval dogs-scavengers given rare scraps-and grew into a proverb of patience rewarded. By the 19th century, Dickens' 1849 'David Copperfield' used it for triumph.
