This happened on a PBR random wi-fi battle. My opponent used Garchomp, Glalie, and Machamp. All I needed was my Starly. His Garchomp used dragon claw on Starly, and it survived thanks to focush sash. I used endeavor and I finished it off with quick attack. Next, when my opponent used Glalie, I used endeavor to bring its HP down to 1. Glalie then tried to use sheer cold and missed (why not a more accurate move?). I used quick attack, and Glalie fainted. When my opponent sent out Machamp, I used brave bird. Both Machamp and Starly fainted.
Me: "Yay! I won!"
Opponent: "How embarrasing. I lost to a Starly."
Also, it annoys me when people with ubers give up because my jumpluff used sleep powder, or when my Shedinja is in battle.
