Anime: Dragon Ball Z
Episode: 109: Black Fog Of Terror
Season: 4
Saga: Garlic Jr.

Arg...I absolutely hate drawing hands. Gohan's fists look terrible.

Meh, anyway this screen shot was during the time that Gohan and Krillen were on Master Roshi's island when Garlic Jr. released the Black Fog. I'm pretty sure it was Bulma who attacked them, but it could have been Roshi as well. I'm almost 100% sure that this is where the shot was from, but it's been forever since I watched the Garlic Jr. Saga that I might be wrong. If it is wrong please let me know so that I can fix the info.
