My husband and I enjoy trying to out-pun each other.  Ok, it's silly, but it's just one of those games that some couples play. 

Last night, we smelled something odd in the refrigerator.  You know, the kind of smell you dread because something has gone off and you really don't want to sniff everything because you will eventually find the culprit right next to your nose as you take the whiff of death.  Anyway, hubby smelled cautiously, but "surprise", he didn't find the stinker.  I sniff and stop quickly at the top shelf.  I said softly and monotonely, "The whipping cream went bad, so I whipped it."  I got the appropriate response: ugh, oogh, argh, oh? ... in that order, as it went from disgusting food realization to the pun to the well, interest in other things marital.
