Ruby code must be beautiful:

----------------------------------
fruit = gets.chomp.downcase

case fruit
when "orange"
	color = "orange"
when "apple"
	color = "green"
when "banana"
	color = "yellow"
else
	color = "unknown"
end

if %w{a e i o u}.include?(fruit[0])
	puts "An #{fruit} is #{color}."
else
	puts "A #{fruit} is #{color}."
end
-----------------------------------

:)


PS: Just valid for 1.9 due to the usage of "fruit[0]".
