Funny you should mention easter eggs, I think they have been appearing in the shops since about bonfire night. Never realised cream eggs were seasonal - I really fancied one in the summer but none about.
The thing is with easter eggs is that they have huge religious significance. Apparently jesus was in a cave and some fucker blocked it with an easter egg, because he had long hair he was dead strong and he rolled the egg out of the way. Mary made him cut his hair off and he lost all his strength so they captured him and made him stand on a cross.
I think that is what happened anyway.
