This picture is an example of an exaggeration because the person has not actually waited an entire year, she is just impatient with waiting.

Oxymoron

"The art of simplicity is a puzzle of complexity." -- Douglas Horton

This quote is an oxymoron because it is complex to create simple art, this is contradictory because most would assume simple art is simple to create.

Wit

A gushy reporter told Phil Mickelson, “You are spectacular, your name is synonymous with the game of golf. You really know your way around the course. What’s your secret?”

Mickelson replied, “The holes are numbered.”

This joke is an example of wit, because witty humor is sophisticated and can sometimes come off as rude. People with a quick mind can pick up on opportunities to make a witty remark.
