We never saw Clark cry on the show, even though sometimes I think it was called for. Numerous authors have made Clark cry, and believably so, in their stories.

Canon: Clark doesn't cry.
Fanon: Highly emotional situations will bring Clark to tears.
I recall only one time Clark cried. After Lois said yes to Lex's proposal he flew to the artic screamed out his heart. When he finished he buried his head in his hands and his shoulders were shaking. I always thought he was sobbing. frown

Also:

I notice that many fanfics show Clark flying to the artic often to think or when frustrated by Lois and/or his feelings towards her. goofy

They also have him bathing in the oceans and lakes to clean up after extremely dirty rescues. Is this canon or FoLClore?
