last-minute ettiquette dilemma

I can't make up my mind. Is it usual to bring a host gift in these situations? What should I bring?

Does anyone need

...a set of rhinestone-studded pink and white Happy Bunny pajamas, slogan "It's All about me. Deal with it."?

Size: Large. Apparently they will stretch to fit a 200-lb man. No, I didn't wear them. No, I'm not going to tell you how I know.

[ETA: Pants taken. Sparkly snarky shirt still available. Cutie baseball style, white with hot pink cap sleeves]

[ETA: Snarky shirt snatched. Awaiting report on its reception.]

p.s. Yes, they are clean.
