First up is Ann Arbor T-shirt Company who are offering "What would Houdini do?" t-shirts on Amazon. They come in styles for men, women, and kids. Should you get one? Well, what would Houdini do?
But if these shirts don't do it for you, how about a "Houdini Keg Stand" t-shirt from Headline Shirts. Not completely sure what to make of these, but do you notice anything odd about the image of Houdini suspended in a straitjacket? I'll update with the answer if someone doesn't guess it in the Comments.
Thanks to Adrian Bianco for the tip.
UPDATE: So the curious thing about this image is that it's actually a photo of Tony Curtis in Houdini (1953) with Houdini's head from his Europe's Eclipsing Sensation poster tacked on.
