He may not have it all, but he certainly does know it all. Settle the score - quite literally - with the Mensa iPhone / iPad app. In just a few questions your brainy companion will confirm what he already knew: his IQ is higher than that of any of his cronies. My suggestion? Don't divulge that you scored seven points higher and are an active member of your local Mensa chapter. If you do, he will predictably explain in great detail how tests of this nature can truly only measure a finite portion of one's intelligence and... *yawn*...

Keep your own high score to yourself and allow him to bask in his own well-deserved genius. After all, you adore his capacity for knowledge and only wish to encourage his mental acumen. Presented properly, Mr. Mental will applaud your discerning gift giving skills. And isn't his appreciation the greatest gift of all?
