man, you've got mental problems

I'm currently having an email discussion with a friend in Chicago (codename: D) about a regularly occurring phenomenon in my (and her husband's) life: the inability to purchase underwear. Here is a recap of my inner dialog, taken from an incident that took place last night while shopping at Wal-Mart:

"wait these are $10. how come. oh there's five of them. this is three for $6. wait maybe i don't want white. I want gray. they don't have gray in a three pack. grey is a two pack. wait, it comes with black. i don't want black. oh there's gray over here. those are $5 each. that's too much. this is two for $6. maybe i should just get the white. $10 is too much. but it's five. wait, i don't even want one white t-shirt. i want gray. i don't need five white t-shirts. but three is $6. these are nine. what brand is this? wait. i should get these. i need to leave."

"oh i could use pajama pants. i don't want that material that gets all the static. wait i have a 33 inch waist but the top goes to 38-40. that's gonna be uncomfortable. oh whatever. what color do i want. wait maybe i should just get the pants big. what material is this? why is that old woman behind me hyperventilating? oh i don't want blue. i don't like this green. wait these are $12 and i need t-shirts."

The only way I can alleviate the pressure of buying underwear is to not buy any; after a 5-10 minute inner conversation I'll ask Gina to help me leave the underwear section.

Is it a male-only problem? D says that it works exactly the same way with her husband, and that "needless to say, it drives me up the fucking wall."

My question is this: Does this happen to you? Does it happen to someone you know?
