Sue: (waving the newly unwrapped riding crop around) Really guys, you shouldn't have...
Jane: It was nothing.
Me: We wanted to get you something practical. Something you could use.
Mary: You mean she has a horse?
Jane and Me: (together, grinning) No.
Mary: (eyes widening) Ohhhhh....
Sue: No, I really mean it. You shouldn't have! I'm going to have to carry this thing around with me all night! In the city! People are going to point and stare!
Me: Well, that was kind of the point. This IS your batchelorette party, a little ritualistic humiliation is to be expected.
Jane: Just be thankful you're not a guy, otherwise you might be naked and handcuffed to a streetlight by now.
Mary: ... remind me not to invite you lot to my batchelorette party.

Actually, we shouldn't be allowed to pick out presents for any occasion. One friend never really forgave us for buying her a large, lifelike looking dildo as a going away gift. But she was moving to the country! And she was single! And I knew FOR A FACT that she didn't have one already!
Really, we were just acting in her best interests. Any amusement we felt at her embarrassment as she opened it at her going away party was purely circumstantial.
