Me: "Hey, what's this?" *holding up an orange tube of some sort of topical cream from the medicine cabinet*

Him: "It's the skin stuff the doctor gave me for that rash on my neck."

"No it's not."

"Yes, it is."

"No. It is not."

"Of course it is."

"No, this is the skin stuff from the doctor." *holding up a similar-sized blue tube*

"Well, then what have I been putting on my neck?"

*gesturing with orange tube* "THIS is athletes' foot medication."

"Well at least I won't get Athletes' Neck."
