There are many things I love about John Barrowman in this series of gifs. His Iron Man shirt for starters, his facial expressions, and his outrageousness and enthusiasm at being able to have sex with a 22 year old on tv.
Mostly the last...I'm 23, can I be on Torchwood? If I can't have Teninch, I'll take Captain Hotsauce.
[Addendum: I don't know why it took me five days to realize this, but I'm actually 22, and not 23. I think the heat and the fasting and the lack of sleep has caused me to age prematurely. Or maybe I've been travelling with the Doctor for a year and lost track of time. Let's just go with the last one, shall we?]
