Self-Inflating Whoopee Cushion

The Self-inflating whoopee cushions by Westminster are completely automated and big on laughs. A Whoopee cushion is an inflatable bag containing a valve at its neck that retains the air in the bag until pressure is put on it (usually by someone unintentionally sitting on it after it has been placed on a chair by someone else as a practical joke), when the air is expelled it makes a funny noise.
