This evening he did a Twitter Q&A. I had a serious question that I posted right at the beginning, but it didn't get a reply. Later I felt like tweeting follow-up questions to replies that other people got. He had tweeted that he doesn't drink tea and to another question he had replied that pies kind of freak him out, so I asked

Fuesch @vuecinemas Is there anything you actually eat or drink? :oP #AskAndrew

and after a while I even got a reply!

That's the second time he mentioned eating wood, so to me it was already a meme. Unfortunately it's really hard to start photoshopping while following a Q&A. But my mind already kept coming up with jokes.

What is Andrew Scott’s favorite cake?

Baumkuchen. (tree cake)

Meanwhile Andrew kept the running gag running (he mentioned it two more times) and so confirmed the meme status.
Half an hour after I got a reply the Q&A was over and I could get photoshopping.
