But I Thought Y'all Only Ate Brown Rice and Superfood

The show last night was good, even though I didn't meet the rock star of my dreams....

I did however de-boat with a riddle. Clearly, I know the answer since I'm the Sphynx...but I challenge you to take a stab at it.

Hipsters are sallow, their limbs thin like Tiggy's.
So how can they gorge on cheese-steaks like piggies? (Especially since they've ALL read Fast Food Nation, I mean please)
