Anime that can make a grown man tear up

I wrote 'tear up' instead of 'cry' because making me cry is like winning a lottery. I'm 26 years old straight male and haven't cried in over 15 years.

I've teared up over some anime, but it would take all of them combined to make one drop of tear.

Some example:
Kimi Ga Nozomu Eien
Anohana
Clannad: After Story
Air - didn't feel it until the end

These have no effect or don't remember much b/c they have no effect in the first place:
True Tears
Grave of Fireflies
Canvas
Kanon
ef: a tale of memories

I could list a bit more, but I'd like to see some input first.

I'd also like to add that I have not tear up or cry when watching non-anime related TV shows/movies as well.

Any input would be highly appreciated. :)

EDIT:
Here's the list of anime I've watched and rated. You can sort them by rating to get a better idea of my preferred anime. Sort by year to see how experienced/old school I am. I'm pretty serious in rating them, so it's very accurate.
