I had some surgery on my shoulder about 5 or 6 years ago, and 
then underwent several weeks of physical therapy. On my final 
visit, the therapist gave me some exercises to do at home, 
informing me I'd need a partner to help me with them. That 
night my husband and I celebrated my recovery with an 
especially boisterous romp in the boudoir.  The next morning I 
told him I had some exercises for my shoulder that I needed his 
help with. With a sly grin he asked, "Did we do any of them
last night?"
