The Facebook has informed me that today is perhaps Dustin’s birthday.
Happy birthday Dusty!!!
HAPPY BIRTHDAY DUSTY!!
I will not call you “Dusty,” but I will wish you a happy birthday. I also won’t use exclamation points.
Have a pleasant anniversary of your birth, you dusty bastard. 
BIRTHDAY YOU!
Happy Birthday!!! (I like using "!"s)
Five exclamation points. A sure sign of a deranged mind.
Jay, just one sign out of too many to count.
