Back when i played saphire and ruby many years ago i did some real facepalm worthy stuff....
What i remember the most tough, was having a friend trade his Latios over to my Saphire.
My stupid child-logic somehow had me convinced that i could breed a Latios with a Latias.
This master plan of breeding a bunch of Latias, and then becoming the cool kid in the school yard, failed epicly to my disapointment.
I spent alot of hours wondering why i couldnt get Latios and Latias to make eggs and when i finally realised it was not possible, i was pretty sad.
