"I'll continue to cherish our great friendship, old pal. But, then again, I'm not known for high standards. Hah!"
"My fondness for you has grown greater with time, my friend. Like the time you loaned me money, I was very fond of you, then! Happy Bday!"
"Dear chum, there is nobody who knows you as I do...and just think, you haven't had to bribe me to keep quiet! Happiest of birthdays!"
"You've been a wonderful friend over these year. May you have all the world's happiness on this special day."
"As your best friend, just let me ask how could I ever possibly forget your bday. Of course, you wonderful wife calls to remind me, but still."
"You've always been one of my dearest and closest friends...which is one mark against you. Well, too late for you to upgrade. Happy b-day, old friend!"
"As your friend, allow me to remind you how darn old you are. I mean, why should I be miserable all by myself! Just kidding old pal, have a great day."
"When you're around, old friend, I don't need anyone else. Happy b-day."
"I looked for joy for many a year. Then, God blessed me with the world's best friend...Yes, I mean you, moron!"
"Pop the cork, it's a special day for the dearest of friends. As if I would need an excuse! Happy b-day, old friend."
"My best pal, you are just like family to me. But, there was that time I hit on your sister, I guess we're an Arkansas family! Happy bday."
"My best pal, without you, even the good times are dull; like a '65 Mustang in need of a paint job. You can see what I've been thinking about! Happiest of birthdays!"
"You've become my best friend over these many years. And, to think I befriended you just to get close to your hot brothers!"
"Old chum, you make a life an all-night party. But, you also have your good points. Happy bday!"
"Friends always. You know you can count on me for a helping hand. And a delicious cake! Happy b-day."
"May you have very blessed of birthdays, my friend. Could I ever possible get by without you?!?!?!"
"Here's to the world's greatest friend. Aren't you lucky to have me!"
"Dear friend, I can't recall a time when you were not there for me. Helping me out of every jam, and picking me up when I'm down. You're the best! Happy b-day!"
"My best friend, without you around, life can be so dull. Then again, I'd get more sleep, so there's that. Happiest of birthdays"
