In TNG episode "Conspiracy":
TROI: Data, it's just not the same. Have you ever been for a real moonlight swim?
DATA: One can swim in moonlight?
TROI: How about you, Mister Worf?
WORF: Swimming is too much like bathing.
Also in TNG episode "Cost of Living" Worf looks miserable in the mud baths but I just assumed it was mud baths but not baths in general.
Is it just Worf or do all Klingons hate baths? If it's all Klingons do they not bathe at all? Is that dialogue from the "Conspiracy" episode enough to deduce that Worf does not like baths or not bathe?
