This looks as if they accidentally picked someone anti-lgbt to arrange the exhibit and that person went out of their way to make the whole arrangement look as absurd and old-school stereotypical as possible. It's like something you'd put next to a "celebrating LGBT recognition in rock" mural that plays Dude Looks Like a Lady on repeat.

It's probably 100% serious but I like to think we have some corporate infiltrators out there.

Edit: Maybe Claire had a hand in this and that it's their way as coming out as "single and ready to mingle".
