Piccolo does a major facepalm as he watches Gotenks spend more time on thinking of ridiculous names for his fighting moves than actually fighting. With all of his antics, Gotenks gets injured and whines "That hurt!" Piccolo replies with a giant facepalm and a "We're DOOMED!" XD

I love that this scene has been used in the "facepalm meme," an example of which can be seen below.
