Someone in my Halloween team is a David Tennant/Doctor (Who) impersonator. I was honestly too busy yesterday to sit and talk to him, but when I walked past their group I overheard they were talking about weird eating combinations (like, someone was eating chocolate sprinkles and mayonaise), so I walked past and said "Uh, I heard fishfingers and custard are pretty good" and the guy just laughed sheepishly and shouted "Wrong Doctor!".
I thought it was quite a funny moment
