I think it was 1961 on a Saturday night, and we were watching Shock Theater on TV. Mom made popcorn, and I was laying on the floor with my bowl of popcorn and bottle of RC. The lights were out, and I remember turning my RC bottle up to drink that last little swill...
Something touched my lip and I jumped up and turned the light on. With the light as background, I saw a cockroach floating in the murky, filmy remnants of the drink.
I've never taken another drink of RC Cola since....
