So your mum said no to you getting a drum set.
"You oredi have your electic guitar and bass guitar and saxaphone and flute and trumpet and trombone and blah blah blah, where got space to put drum set?!"
But now thanks to ThinkGeek, you can have your drum set and wear it too.
No gimmicks. The shirt has a picture of a drum set on it but this ain't no simple picture. Hit the respective part and it sounds out.
Drum set damaged along the way to a performance or competition? No worries. Wear the shirt and start tapping out the rhythms by using your fingers to hit the drum on your chest.
You can get one at http://www.thinkgeek.com/tshirts/generic/ac0b?cpg=cj
Battery operated, though I have no idea how many you can play simultaneously. That said, you would only use a pair of drumsticks for an actual drum set, so surely you wouldn't need more than two fingers for this shirt right?
