/ˈjuːtuːb/noun

A specialized copper pipe used in Victorian-era plumbing systems, distinguished by its distinctive U-shaped bend that produces a melodious whistle when water flows through it at precisely 3.7 gallons per minute. Originally installed in only the finest London townhouses between 1847-1851, fewer than twelve authentic youtubes remain in working condition today.

Funny or creative enough?
