unintenuendo

An innocent phrase full of unintended innuendos.

I got new mounting brackets and insulation for my hot water pipes to keep them lifted and separated so they don't rub together and bang all night. I'm going to sleep so much better now with my plumbing properly mounted! Whoops, that was an unintenuendo.

(see Sexually Oblivious Female meme)
Unintenuendos provide great opportunities to say, "that's what she said!"
