Anime related item you are embarrassed you have watched

Sacred Blacksmith. I still don't know why I fell for someone's ruse when they told me the ending would make up for its shoddy quality and flimsy story.

The most embarrassing thing is that I watched all of Serial Experiments Lain while thinking it'd try to explain itself by the end of the anime. Then the last episode started rolling the credits and I felt like I wasted too much time chasing a fantasy. -_-

..... Since everyone is being honest. Boku no Piko.. >_>;;
