Had a long, exhausting Tuesday, so I'm keeping this short.
Will be posting the video for NKOTB Nostalgia Week II late, along with the Daily On The Set pic over at my spn_ontheset comm. Sorry, everyone. I'm just too tired to post them this morning. It's all I can do to get this cap posted. Look for them later in the afternoon.
