Lentils and Spaghetti Squash?

Last week, in an effort to eat random pantry items, I found myself making a bag of lentils... I remember eating them as a kid and they were pretty good, and I love all the flavors I add to it, like carrots, tomatoes, Ketchup, mustard, onions, salt and pepper, etc.
The funny thing is, most anybody, besides my family, has heard about them!
When I told Jason what I ate for lunch he asked, "What is it?" As if it were from another planet or some nasty gross tofu type meal.
The same thing goes for Spaghetti Squash. I bought two of them on Monday but couldn't remember how to make them. So, I called my mom, no answer, I called Lori, no answer, I called Natalie, no answer, then I called Rachael (who I thought was my sister, but realized that I had saved my friend Rachael's number under "Rachael's" name) and she answered.
"Hey, do you or your mom know how to make spaghetti squash?" "Um... my mom does, let me ask her..." when she came back on the line she started telling me how to make spaghetti, the pasta! "No, I mean the SQUASH!" "Oh, no, I don't even know what that is!" she said.
I finally called my sister, Rachael, and found out how and made it and it was so yummy!
How can people be missing out on these two items that are really inexpensive (lentils = $.98 per bag and the squash was only $.33/lb at about 3 lb's max!)
Either way, I feel like I grew up on a farm, and no one can relate, but all it takes is a good recipe and "hey, wanna try a bite?" to get them to like it, right?
