Hmm... both of these involve Latias, just different versions... *Hopes that the "funny" in the topic can be either funny "weird" or funny "ha ha", cause these are more of weird*
Once, when looking for Kyogre in Emerald, I was like, five steps away from its little cave, and... BLAMMO! Wild Latias appeared! *Uses master Ball due to the annoying fact it runs*
In Ruby, on the Southern Islands, I was trying to weaken Latias, but it kept using Recover... I was like, "Screw this", so I just started throwing Ultraballs *Has 24, forgot to buy more* It broke out of every single one of them... and other than Ultraballs, all I had were two Pokeballs. I threw one of them, and then like, showed this girl I knew sitting right next to me, was like, "Watch this!", and... shake/shake/shake/BAM! Latias obtained by the first Pokeball I threw
