TIFU by telling my wife she needs Weight Watchers

Obligatory, this was last night, not today.

So my wife and I are lying in bed last night watching television as we go to sleep (like we do every night). She has had cold symptoms starting for the last few days, and has a girl's trip scheduled for next week. A commercial comes on for Zi-Cam, which claims to shorten the length of time you have a cold if you take it when symptoms first begin.

So me, being the concerned, loving, devoted husband I am say to her "That's what you need". The TV commercial programming gods hate me - what I didn't realize was, she had just started falling asleep, so by the time she opened her eyes the Zi-Cam commercial was over and instead was a Weight Watchers commercial.

She's been struggling with weight gain recently (hormonal) and needless to say was none to pleased with my recommendation.

TL;DR: Suggested my wife needs cold medicine but instead suggested she needs weight watchers.
