Hey, we all know youtube breaks most user videos into 15 min chunks. Well you can bundle/stitch them up in a playlist, and post the playlist here.

How to make embed a playlist. might be a better way but just humor me.

go to the first video
below the video, click the untitled dropdown button right of the add to button.
select new playlist at the bottom of the drop down list.

put in a name for the new playlist

go to next video, click the untitled dropdown button right of the add to button.
the new playlist should be in the list. click.

repeat as necessary

click your name up at the top of youtube
"my videos" should appear in a drop down list. click.

click on the new playlist on the left column

crap appears to the right. At the top of the crap click the share button.
embed code is right there. You're done!
