Last night it was my step dad and I...but I was the one who made him feel "clueless"...
I can't remember what exactly brought up the subject but I said "the movie Mars needs Moms"...
He said "where is Marcy sending her mom?"...(Marcy is my SIL)...
My mom and I just looked at him and both rolled over laughing...
I say and do things all the time that my husband just gives me a look like "oh honey...that's just too far out there even for you!"...
Like when I had the brilliant idea to wash the curtains. And so i was reading the label on how to wash (after I washed them) and said "How am I supposed to lay these flat to dry? Do they think I just have a table 12 feet long?"...he looked up from the other room and calmly and with no smartass tone, and straight faced said "No honey, we are going to hang them back up wet!"...
ETA: My daughter and for some this won't be as funny...when she was three my husband and I both worked from home and we were leaving one day and she said "Dad you left your peter on"...STOP! "honey what?"..."Dad left his peter on"...(yes I looked!)...so I said "show me what you are talking about"...she walks over to the laptop and says as she points "dad left his peter on"...
She then a few weeks later rec'd one of those kid computers...and in Texas Roadhouse announces "Grandma I just LOVE my peter!"
Yea...explain that one to a restaurant!
