Not exactly the same, but when I worked as an _intern_ for a program funded by NASA, my grandmother ("Nana") used to tell her friends I worked for NASA.

You should definitely get her a t-shirt that says NANA in the style of the NASA logo. Surely someone else has already designed it and is selling them online.

My mom used to say I "worked for Google" (back when that was considered respectable) when I participated in Summer of Code one year.

In that case, I also worked for NASA!

...as an intern for a computational engineering program in Chattanooga, TN, where I changed RAM in servers. We received like $10k in NASA funding.

It's impossible to say Nana shouldn't be in the comments! She is every bit as good as Mom for an HN comment!
