Pie Breakdown

I present to you some very scientific proof that Shephard's PIE = pie

(borrowed from Threadless Ts)

The tale of Four & 20 Blackbirds dates back at least to the 18th century.

Also present here, we have Shepherd's Pie - not to be confused with Cottage Pie.

Though I am somewhat confused by the apparent popularity of Steak and Kidney pie in the chart presented......
