Every once in awhile you fall into something that

Every once in awhile you fall into something that jumps to something else. Maybe it's relevant, maybe it's not, but just maybe it fits into something that someone else has a handle on.

Reminds me of a story of 2 farmers on the barn roof, and their ladder had fallen down. One of them spotted a pile of manure and suggested that they jump into it. First guy went and yelled back up, "Nothing to worry about, it's only ankle deep".

Second guy jumps and is in clear up to his neck. Spitting mad, he yells at the first guy, "I thought you said it was only ankle deep!?!?"

First guy replies, "Well, I jumped in headfirst."
