There are a few more gems to be added to the phallic logo collection.
First up, the aptly named "modern tvätt [1]", I'm not sure if this logo insunuates that they only wash soiled sheets or not. But it sure is ..eh..modern.

Then there's Benton and Overbury [2] which might as well have been named bend over. What is that, a butt with a tramp-stamp?

The biggest dick of neon signs created this monstrosity [3].

Lets not forget our old favorites, kudawara's [4] accidental sex.

The "Instituto de Estudos Orientalis" which we named the best logo ever [5] because before this we didn't know that studying 'orientalis' includes butt-sex.

The by now classic (and since the internet uproar about it, redesigned) The Arlington Pediatric Center [6]

And an honorable mention goes to the fantastic art direction of this slab of meat.
