you mentioned neat so it reminded me of my all time favorite scene in Friends.
Ross is with Emily (young girl) in their summerhouse/whatever when Rachel and Emily's dad (played by Bruce Willis) enter the house. Ross hides under the bed of the dad and hears him speaking to the mirror.
He says things as "you're going to get lucky! and you know why? Because I... am ... a neat ... guy!" then he shows off his muscles and a bit later does a little dance singing "I'm just a love machine."
Later on, they discover Ross and the dad wants to kick him out, prompting Ross to say:
"Oh, I don't think he will do that... because he will find out that I'm also ... a neat guy."
He then moves over to the dad and does the same dance singing "I'm just a love machine!"
The dad looks totally pissed off and yells "ROSS!", then calms down and says "let me show you your room"
it's bloody hilarious
