Duker syndrome 

A syndrome that effects all people with names that rhyme with Duke.

Symptoms include retardedness, unfunniness and an addiction to flavored air.

Some people with the syndrome can suffer from silly goofiness. They also attempt to pass of the disease by approaching victims from the back and breathing on them silently. If they stand behind you for over 10 minutes without you noticing or smack their nic for more than 10 times in a row please contact a doctor immediately.

Lucas was just officially diagnosed with Duker Syndrome when he sat in his room alone on a Tuesday night smacking his cart.
