Thingmabob

"You know, if you can't fix it with a hammer; you have an electrical problem." Brian piped up from beside the machine where his brother was working.

"Hand me that doohickey will you?" Mark asked, reaching out from under the machine.

"Which dojigger are you taking about?" Brian responded, sitting in the chair and looking at all the various tools.

"The doodad that is curved at the point," Mark replied, rolling his eyes even though his brother couldn't see it.

"Don't roll your eyes at me," Brian said, "There are six doodads with curved ends. Which one do you want?"

"Just hand me any widget, just make sure it's not to big," Mark said.

Brian handed Mark a tool that vaguely resembled a curved vice grip. "Here." Brian watched Mark struggle with it for a moment, "are you done yet?"

"Nope, we're missing a thingamabob." Mark said, crawling out from under the machine.

"What kind of thingamabob?"

"A switch type button thingamabob that will reset the unit." Mark made a vague motion with his hands to describe the piece.

"One like this?" Brian held up a bit of machinery.

"That's it!" Mark whisked the bit from his brother and crawled under the machine again. A few seconds later the machine gave a heave and rumbled to life.
