Dear 100 Hour Board,
What should I do on a blind date with a blind date?
-Can't See a Good Solution
In general, something quick, relaxed, and involving some kind of food is usually good to do on a blind date. Something like getting ice cream or hot chocolate. I can't think of any reason why you couldn't do this with a blind date either.
May I just say, however, that blind dates are the worst? The ones you go on, that is, not the ones you go with. This extends to any date with someone that you've never spoken to aside from asking them on a date. The get-to-know-you stuff that usually happens naturally in the first five minutes of a non-date conversation always (in my experience) ends up awkwardly taking up the entire duration of the date. It's definitely one of the worst ways you could get a first impression of someone, and one of the worst ways you could give a good first impression to someone else.
You should totally do what Kenneth from 30 Rock did, namely, pick your date up in a car, drive around randomly for a bit, then head to your apartment. Insist to your date that you're going to a very fancy restaurant. Once you enter, have your roommates act like they are a fancy maître d', waiters, and fellow patrons at the fancy restaurant. I'm sure your date will be super flattered and not at all insulted that you sought to take advantage of their physical limitations in an attempt to make yourself look better.
Actually, scratch that. A better idea would be to attend some sort of poetry reading or book club or concert or anything else that focuses on the ears rather than the eyes.
