Actually, I got a bigger kick out of the term Heavy-Duty. After looking it up, it comes back as:
Main Entry: big
Part of Speech: adjective
Definition: large, great
Synonyms: a whale of a, ample, awash, brimming, bulky, bull*, burly, capacious, chock-full*, colossal, commodious, considerable, copious, crowded, enormous, extensive, fat, full, gigantic, heavy-duty, heavyweight, hefty, huge, hulking, humongous*, husky, immense, jumbo, mammoth, massive, mondo, monster*, oversize, packed, ponderous, prodigious, roomy, sizable, spacious, strapping, stuffed, substantial, super colossal, thundering, tremendous, vast, voluminous, walloping, whopper, whopping
All wonderful advertising descriptions...no wonder people get duped.
