This may be one of the most inexpensive, yet absolutely hilarious gag gifts we have ever seen. Perfect for pretty much any kind of party, the Grow a Girlfriend and Boyfriend will quickly become the centre of conversation. Simply drop it in water and watch it grow. It starts to grow after 2 hours and reaches 6 times the original size in 72 hours. Once taken out of water it will shrink and can be re-used.
