"Wish I was 6 again" joke

A man was sitting on the edge of the bed, observing his wife turning
back and forth, looking at herself in the mirror. Since her birthday was
not far off he asked what she'd like to have for her Birthday. I'd like
to be six again, she replied, still looking in the mirror. On the morning of her Birthday, he arose early, made her a nice big bowl
of Lucky Charms, and then took her to Six Flags theme park. What a day!
He put her on every ride in the park; the Death Slide, the Wall of Fear,
the Screaming Monster Roller Coaster, everything there was. Five hours later they staggered out of the theme park. Her head was
reeling and her stomach felt upside down. He then took her to a McDonald's where he ordered her a Happy Meal with
extra fries and a chocolate shake. Then it was off to a movie, popcorn, a soda pop, and her favorite candy,
M&M's. What a fabulous adventure! Finally she wobbled home with her
husband and collapsed into bed exhausted. He leaned over his wife with a big smile and lovingly asked, Well Dear,
what was it like being six again? Her eyes slowly opened and her
expression suddenly changed. I meant my dress size, you dumb ass!
The moral of the story: Even when a man is listening, he is gonna get it
wrong.
