When I recently bought a t-shirt from a company called East
Beach, it came with this instruction sheet, which I found amusing:

OPERATING INSTRUCTIONS:

Pull garment on over head, placing arms through appropriate openings.
Finish with label at back of collar with design facing out.
_Fashion note – tail can be worn out for casual or tucked in for formal_
Wear shirt to pre-determined occasion.
_Important note – remove all tags or labels, such as this one, before
wearing in public_
After shirt is sufficiently soiled, place in washing machine (note –
for best results remove shirt)
Leave the shirt just the way you removed it – inside out. Wash warm
water/cool rinse.
_Note – Xtreme shirts are NOT underwear – dont let your mother throw it
in hot water, and keep her away from the bleach_
Dry on low heat, air or line dry.
Return garment to right-side out and repeat step 1.
