I once searched for something with the word "blue" in it and got all kinds of vivid obscene results. I guess I am not very educated in the lingo because this happens quite frequently when requesting something that is seemingly innocent in nature.
If I am aware before I request I can rephrase. Kind of like looking in the Yellow Pages. I once needed to call the local "Dump" but looked and looked and couldn't find a number. Finally got a cross reference and found it under "Sanitary Landfill". I guess you need to have a college education to use the Yellow Pages.
