I'm sure you already knew about Starscream and Ironhide's tendency to banter at one another over their commlinks...
But you didn't know that Starscream contacted Ironhide on a nearly nightly basis during his pregnancy to complain about happenings around the Decepticon base. Woke him from recharge and everything.

Ironhide - colored by me]
Hilarious sidenote: While I was coloring this, a friend of mine saw and questioned of Ironhide: "Why does he look like a deadbeat dad?" Hah. Haha. XD
