I hate commercials

You know the one, it comes on every night during the news.
ED.
Erectile Dysfunction.

This morning C says he needs to talk. He wants to know why the commercial says to "see a doctor if an erection lasts more than 4 hours"?
"Well..." I start to explain.
C- "I mean, I get nervous when mine last longer than 4 minutes."
I literally spewed coffee all over the kitchen. Had to clean coffee off everything. That is why I hate ED commercials.
