Hey Bob, you order two thingamajigs?
No Dave, I ordered whatchamacallits, just like you said.
Bob! I specifically said I wanted two thingamajigs, and you got whachamacallits!
Sorry, I got confused, they look so much alike.
Alike? They look nothing alike. Thingamajigs are smaller than whatchamacallits and with less color. Like someone else I know.
