WTFF?

I do not understand how these stupid podcasts work. I subscribed to three different ones last night through iTunes, downloaded them, and synced them to the iPod. I even checked several different times in the iPod menu that there were six items under the main podcast menu on the iPod. I was all set to listen to them here at work, when I go into the main menu and it tells me "no podcasts". They were just there last night, why the hell would it delete them? I thought Apple products were supposed to be user friendly. =(
