Watch This! – Lung Capacity Test Prank – Video

(iWIDK By Keith Goulette) - Well that’s mean.

A man pulls a prank on his friend with a “lung capacity test,” check it out.

Only the British could pull a prank on someone and have both parties react in the most polite of manners.

Seriously, the victim here does nothing but look at it weird and say “uh, well, it didn’t happen to you but it happened to me… How does it work?” While the prankster just sits there giggling to himself.

If obnoxious Americans did this someone probably would have been left wounded.
