How do you use effrontery in a sentence?

Effrontery is essentially "barefaced" insolence, audacity, temerity, or simply "nerve." It can be an insult or mere presumptuousness. It can take many forms, from the naive to the callously bold. The less calculating version is the chocolate-covered 4-year-old who insists he did not eat your candy bar. On the brazen side is the hurrying commuter who knocks you to the floor, and then insists you pay the cleaning bill for the coffee he spilled on his coat. Sometimes it is used to mean impudence, as to an authority or royalty. A tourist might display effrontery by telling the Queen to move her carriage so that he could get a snapshot of Westminster Abbey.
