I'm a Dinosaur

As you may or may not know I work with a lot of younger people when I do pizza. While we do have a group of seniors who work also most are young. I seem to be right in the middle of the bell curve. Anyway we talking and I can't even remember how the flow is going. Anyway I say underwear and one guys stops and looks at me and says, "Underwear? My dad wears underwear and he's 56." Okay I didn't know underwear is now a foo pah. Now boxers seem to be the topic with a few jokes at me. So I make a joke about in my day I had to walk 20 miles uphill in the snow to buy a pair of moth eaten underwear and I loved it. They look at me and for some reason my comment starts a talk on how they got to school. Whether their parents drove, bus, etc. WTF! What are they teaching these kids of today. Standard jokes go right over their head. I would like to say it's the new math, but since it's old math now I don't know what to say.
