Team Fortress/Azumanga for me
What about you, /a/?
Touhou and WH40k
DON'T DO THIS TO MY PRECIOUS TF2
Bottom panel makes me laugh every time.
The Jump Stars games were good Crossovers :/
Unless you mean ones that don't already exist...um.. Zoku Sayonara Zestubou sensei+Portal would be extreme XD
this makes me lol everytime
I didn't save it, but I did once see a Fresh Prince of Bel Air/Higurashi crossover.
Lucky Star + Hotoku no Ken + School Days + Dragon Ball Z + Tengen Toppa Gurren Lagann + Boku no Pico
BnP for those who like Shiraishi, Hotoku no Ken for the Anime Tenchou fans, School Days for those who want to see hot lesbian sex with someone dying, Lucky Star because it's a staple, and Tengen Toppa Gurren Lagann for the abstract Gainax awesomeness.
age for tf2/azumanga crossover
