I recall one night about 40 years when I woke up to a squishy feeling when I laid my hand next to my head on the bed. I wondered what it was, and turning on the light I found a fat tick. I pulled the covers back and found a dozen more.
I was single at the time and my dog was sleeping at the foot of my bed. I checked him and he was covered with blood engorged ticks. We had been out fishing down by the river that day and he must have picked them up there.
Took a couple of hours to remove all the ticks from my dog and change the sheets before I could go back to sleep.
Oh my God!! And here I was worried about a lousy cockroach!
