I got that you were going for a "Tropic Thunder" ref, but it doesn't fit. It sounds like you're saying ebay is stupid, but the TT is satirizing actors pretending to be stupid. And, TT gets away with the bit because it pushes PC-ness further towards not shitting on mentally disabled folks. Mayhaps it should, but slang use of the word "retarded" doesn't automatically offend me. I just don't think your use worked.
