For my friend's birthday, I put his gift inside another box (a tea kettle one just as a joke). When he thought it was a tea kettle, he was VERY excited because he said he thought his other friends had told me that he needed a new tea kettle. His old tea kettle wasn't optimal apparently. Then he saw that my gift was NOT a tea kettle. haha.. that's the last time i put a gift inside a different box. :D
