They're not shamrocks, they're clovers. Shamrocks have three leaves. God Bees, get it right!That just looks stupid. If you're going to get tattoos at least get something that's not tacky like matching shamrocks on your hips.

As the resident Irish gay I can tell you that he's clearly not that 'Irish' if he got that wrong.
Dany, as for nerdy tattoos, there was a guy who used to be in my research group who got a tattoo of a double helix on his upper arm. James Watson visited our university a few years ago and he got a picture with him showing off his tattoo. Now *that's* nerdy. There are actually quite a few pictures of his tattoo floating around on nerdy tattoo sites.
