There are a few t-shirts on the daily deal from eBay Canada today. They are funny t-shirts, and are only $9.99us with free shipping. They’re being sold by Cafépress which is an international t-shirt printing company, so a reliable seller.
Just in case you don’t get it, the “I’m on a boat” phrase comes from the recent spate of Old Spice ads. If you have never seen them, well ladies, you MUST watch the first one... and hopefully a few more.
The others you can choose from are “oh snap” or “afternoon delight.” I think the latter is from the song in the Anchorman movie? Correct me if I am wrong :)
