(My husband has just made himself a bowl of ice cream when I interrupt him with a kiss.)

Husband: “Stop! You’ll melt my ice cream!”

Me: “No. The temperature in the room will melt your ice cream, but not during a two second kiss.”

Husband: “No. Kisses cause friction. Frictions cause heat. Heat melts the ice cream. So, you melted the ice cream.”

Me: “I’m pretty sure our scientific debate on the properties responsible for melting your ice cream allowed the heat of the room to melt your ice cream.”

Husband: “But if you had never kissed me, this conversation would have never happened and therefore non-melted ice cream.”

Me: “Shush and eat it already, will you?!”

(He finally gave up the argument and ate his ice cream, which, by the way, was slightly melted.)
