One year, we decided to set up a train set near the tree. We have a collection of very small trains that borders on excessive. (Okay, it is plainly excessive, but at least they are small.) Because the trains are so small, to show them off properly we wanted to set them up running in front of the tree. Because the tree was rather small it was on a table.

Cleverly, we put a board on the table, but sticking out in front so the trains could run around in front of the tree. How wonderful!

So spectacular, in fact, that when the cat jumped up to explore the train platform it catapulted the tree over the train, and the whole mess ended up in a wet pile on the floor.
