My bff and i have joke that i am married to spongebob and she is married to elmo. I bought a stuffed spongebob to take the joke a little farther and i would like to get spongebob underwear to tie it all together. however, i am a cheapskate and will only buy them if they are cheap. I looked at walmart to try to find some but didn't see any. Do they even sell such a thing in womens? If so, where?
