I think it depends on the item itself. I've gotten a Tension Titty on here and it's the talk of the town! Ha ha. Whenever anyone comes over, they all have to squeeze it, and it's so silly and fun. And, we've also got a penis ice mold. It's fun and whimsical, and who doesn't love a glass full of ice dicks?
I might give a close friend a gag gift, but it'd need to be well made (like the titty or ice cube tray) or else I wouldn't bother. I wouldn't buy them something that would easily fall apart.
