Haven't been on here in a while, but just finished two Doctor Who inspired tshirts. Both have quotes from episodes that I find particularily funny. Both freezer paper, with Setacolor fabric paints (black transparent, buttercup yellow opaque, white opaque, orange from mixing cherry red opaque into the yellow). One stencil layer for the first, two for the second (black base, then white and yellow for the next layer).
The first is a quote from the Christmas episode, "The Christmas Invasion", David Tennant's first full episode. The quote refers to the Doctor's disappointment at not being ginger (red haired). He then yells at Rose and suddenly says "Ohh that's rude! Is that the kind of man I am now, am I rude? Rude and not ginger."
The second one is in reference to the Doctor's fondness for bananas. He references them often. In fact, in one episode, he once claimed to have invented the banana daquiri a couple of centuries early (at a ball at the Palace of Versailles, Paris). As he told Rose, "Always take a banana to a party, Rose; bananas are good!"
-EDIT- I've removed the picture for this one. It suddenly occurred to me where I got the image to make the stencil from in the first place, and decided Cafepress might not be too happy!
Hope you like!
