There are times when you find something funny. It tickles your funnybone. You haven't seen it before, so reading it doesn't give you the polite "ha ha", but rather the "laugh from the guts so hard your stomach hurts and your eyes water" laughter.
I'm pretty sure these snippets of humour, when they first came out, were damn funny to me. Else, I wouldn't have saved them. The fifth time I've read them, though, maybe not as funny.
