Forbidden Romance

I finished my plain STR socks earlier this evening. I had to finish the toe and knit the afterthought heel with a leftover ball of Trekking XXL. The STR is lightweight in the color Waterlilies.
On the drive home Mutti and I were admiring my socks. The following dialogue occured:

Me: "Well, they look goofy, but at least I got to use two of my favorite yarns. They're together - at long last."

Mutti: "They could mate and have sock babies."

Me: (making socks "mate" - hey, it was late, we were tired.)

Mutti: "Don't do that in the car! They'll get yarn come all over!"

Me: "Wouldn't that just be yarn tail?"
