Isn't that amazing? And yes, it's a wig. MTV filmed a series of joke promos for an Al "Unplugged" special in which everything was earth tones and acoustic guitars and they made him up like this for the spots. It caused quite a stir, apparently...tons of people thought he'd cut his hair off. So many people told him he looked great with this haircut that he actually considered cutting his own...until he realized that if he DID cut his own hair off it would look nothing like this, it'd just be spherical. This is the regular Al without the wig:
Just thought you'd get a kick out of that. Have a nice day!
