Take your pick

an academic treatise conducted by Indian scientists, working at a government institute, on adolescent nose picking.

The 2001 report found that nose picking is the same across social classes. They also found that about 80 percent of teenagers do it exclusively with their fingers while the rest are split almost evenly between using tweezers and pencils as their excavator of choice. Delving deeper, the good doctors found about 50 percent of people pick to unclog their nose, while 11 percent do so for cosmetic reasons and a similar number do it just for fun.
