I put my pet hamster in the bath sink to clean his greasy fur. He had seeds in his pouch, but pushed them out of his pouch in the sink (he kinda doesn't like water). I thought I had picked them all up and threw them out, but apparently some went down the drain. Well, a few days later I see this long stem sprout coming up through the bath sink. It took me awhile to figure out where that came from, but when I did I thought it was hilarious. It was a beautiful sprout too.
