Irony: the juxtaposition of two disparate yet connected items.

I'm proofreading the Master Gardener Manual. My project for the evening was to read Section 17 on Pesticides. As I neared the end of my pages, I felt some tickling on my arm. I brushed a huge Jerusalem cricket off my arm onto the recliner. She's in a box now, waiting to be taken to the lab tomorrow! I wonder what Stella would name her . . .
