Help! I'm stuck on a table

My sim went to GeekCon and I suppose it wasn't supposed to be there. All the stalls and con events were piled on top of each other and weren't functioning. My sim ended up on top of a table and is stuck. Since GeekCon isn't on the calendar,  I don't know when it's supposed to end. Is this his new home? Will he get fired from work? He can't even sit.
