All the Fun of the Fair

Some background, Sam is excavating in Durham, He-Who-Cannot-Be-Named wanted to see the excavation so I put the two in touch. He went to see her and I received the following text messages:

Him: I went to see sam's dig. She got all the other people to hold me down in the dirt while she stamped on my stomach. 'this is from alex' she said. It was awful.

Me: Well I guess she only did it because you deserve it. I don't remember telling her to do that but i guess i must have.

Him: I don't care whose idea it was, it has ruined my afternoon

Me: That was the plan. So it's worked?

Him: Yes. Even the dig was fake, the thing was an elaborate hoax to humiliate me. I guess it was you who arranged all my students to be there too. Jerk.

Me: That was me! I admit it! Was your departmental head there as well? He was invited.

Him: He couldn't make it. He sent his wife and kids though. There was a candy floss seller and a small funfair, and donkey rides. Everyone was having fun except me.

Me: I did tell the mayor of durham about it so he must have set the whole thing up. I had nothing to do with the funfair. I'm pleased it came off though.
