Finglonger 

an invention by Professor Farnsworth...It is a glover with the pointer finger extra long so you can poke things farther away. It wasn't actually ever invented...someone should invent it.

"And thats what life would have been like if I had invented the finglonger, one can always dream, one can always dream..." said Professor Farnsworth
