When a casual blog written by a housewife, Mrs. Jones, about her sexual adventures with her impotent husband goes viral and becomes a rage, Mr. Jones has to decide between self-respect and the money and instant stardom staring the couple.

I think it’s a pretty funny concept- very timely and easily understood. It’s a bit wordy, and you have to make sure the spelling is correct (I assume you meant “starring”).

“When a poverty-stricken housewife’s blog about sexy adventures with her impotent husband goes viral, she must decide between her self-respect and dignity, or instant fame and fortune.”

You can ratchet up the irony- and conflict/comedy by highlighting her possibly being religious, or her assuming that the blog was anonymous, or having her husband be a very prestigious man in town, or something along those lines.

Hope this helps!

staring (at) the couple.
