Pranks are the funniest thing ever for some (usually the pranksters) and a reason for major annoyance for others (usually the victims). Some pranks are seriously deranged and over the top, some are harmless fun.

A mosquito won’t cause serious problems, but it will disrupt your peaceful sleep. But is there a mosquito?… It might just be your best buddy trying out the Buzzing Mosquito – Light Sensitive Sound Box.

This toy is darkness activated – which means it will start making noise when you turn off the light and will be quiet when the light is on. It will take a long long while for someone to realize there is no mosquito hiding in the dark, only a prankster laughing his ass off somewhere.
