Midnight Tea

Fenton's house is a mess. Not only that, the power went off during the night because of a hurricane.

Still, Fenton wants to have a midnight tea party for him and his three associates. Fenton needs to get four matching cups out of the cupboard, but he can't see into it. Fenton has three different teacup patterns. One set has 6 cups, another set has 8 cups, and another set has 4 cups.

How many cups does Fenton need to take out of the cupboard to ensure that he gets four matching cups?
