PHILADELPHIA (CBS) – O’Christmas tree, O’Christmas tree – the Mutter Tree is going up again.

According to the museum’s Facebook page, they’re looking for “offbeat” ornaments to hang on their lobby evergreen.

“As you might imagine, our tree is a little offbeat, and features ornaments based on some of the more iconic items in the museum,” reads a post on Facebook.

Above the post is a photo of one of the museum’s previous trees, hung with baubles such as two-headed gingerbread men and what appears to be a piece of cardboard advertising “The Clap.”

Details on dropping off or mailing your wacky holiday décor to the museum can be found here. And be aware – any ornaments you offer become property of the Mutter.
