i know there like super glue, but hte hardest part is picking your nose without anyone knowing, that is an art form my friend
i like to use the "one finger scoop" (ram finger up and turn quickly to exctract booger)
if htat doesnt work i follow it up with a few quick "nose thrusts" (blow out little are from nose rapidly), finally i finish the nose dweller off with a "nose scratching" (pretend your scrathing your nose, but your actually luring the ah heck out) this is the part were u actually pick out hte little guy and get him on the finger.
once he is on your finger u can coneal him in many places, u cna get creative, under a desk/chair/back of a book u cna get creative
