If you checked out the May 12 episode of How I Met Your Mother, there was another story line that didn’t involve Britney Spears. Marshall and Lily have to sell their stuff at lilyandmarshallselltheirstuff.com to pay their growing expenses.

As these things go, Lily and Marshall Sell Their Stuff (.com) is real — visit LilyAndMarshallSellTheirStuff.com and you’ll be redirected to a charity site. You can bid on a number of items, and all proceeds from the sale will benefit Childrens Hospital of Los Angeles.

How I Met Your Mother delivers more than just laughs, it seems. Bid on items like a signed script, a suit worn by Barney, shirt worn by Marshall, Marshall’s robot monkey head, dresses worn by the ladies of HIMYM — and the ultimate, a chance to visit the set and meet the cast of How I Met Your Mother.
