history: I was visiting the new house house of a friend. I wanted to surprise him so I did not knock on the door. So I entered the house, but it was the wrong house. So I yelled "Surprise ! " to a complete stranger in his house. I apologized to him. That's so funny! How did they react when you did that? They were surprised_comma_ I apologized and exited the house as fast as I can. My face was red. 
current: I would've been so embarrassed if that was me. At least you've got a funny story to tell people.
next: Yeah, this story had more success than the gift that I brought to my friend.
