Pop-Tart in the Toilet

When I was about 13 or so, I was at my friend's house and he gave me a Frosted Pop-Tart. I only ate half of it, and I didn't want the rest of it, so I threw it in his downstairs toilet. I was at his house the very next next day, and we were talking about Pop-Tarts for some reason, and his little sister yelled "Yesterday I found a Pop-Tart in the toilet!" I looked at my friend like "What is she talking about?," and he shook his head.
