Wedding shower etiquette question

[TsPoet]

You could be in touch with whoever is organizing the shower and see if there is some sort of theme. I was once at a bridal shower where the theme was directly related to the bride and the idea was to bring something small and fun within that theme.

I had a good friend who was going to marry a man with the last name of Ham. She asked for pig items, she decided she was going to start a pig collection. I bought her some household things off her registry for the wedding, but when I was invited to the shower, I thought I'd get her something more in tune with her fun side. Their shower was coed but small and included her future in-laws.
Did I mention, she told me she was going to start a pig collection? I want to re-iterate, she told me she wanted pig things. Just to make it clear, she asked for pig-related items.
Her father-in law was about as Angry as I've ever seen anyone when she opened the pig-shaped tea kettle I was so excited about finding for her.
I guess growing up with the name and being a police officer named Ham inhibited his pleasure in things pig-like.
