I love the commercial…don’t worry I’ve got you. The kitten, especially…hope it found a good home!
Mr Mattar,
I love your commercials. My favorite is the one where the waitress asks the dummy “Are you single?” It is so cute and humorous. It would be great to see her again. Should I ever need legal advice, you would be my first choice.
Mr. Matar,
Can’t believe there’s an opportunity to leave a response! For the longest time, I’ve told myself…I wish I could.
Like many other comments before mine, I too am a fan of your commercials. Your Mom adds much to the enjoyment of watching, too. Whoever is your marketing person or people, please let them know they do an awesome job! Also in agreement with another comment, you do portray being a very humble, down-to-earth, simple, salt of the earth kind of person. Not many lawyers come across that way if any at all. Another thing I keep telling myself, if ever an accident lawyer was needed, I’d call you to take on my case but more just to have the opportunity to MEET you!
We love your commercial and hope you win! My husband would like to know the name of the restaurant featured in the commercial. He. Would love to try that steak!
Any help would be greatly appreciated…Happy New Year!!
I have worked my entire life in pre-k working with 4-year-olds. Once when I was testing them I asked this one little boy if he knew his telephone number. He said no but I know that important number. I replied with oh you do? thinking he was going to say 911. He looks me square in the eye and with every ounce of pride recites yes! It is ! I died with laughter. I never forgot that kid and thought you would appreciate the story!

We just LOVE your TV ads. They are the BEST! Please do lots more, they beat that lizard, the other two who just split up. and that woman who walks about in white pants and an apron, selling boxes. (That’s really weird!)
We love the one where you are chatting on the bed with your mum, and the other where we think you’re picking up after Peanut Butter.
Keep up the good work, and thanks for the chuckles.
What is his net worth??
Love your dog Peanutbutter
Really enjoy your tv ads. I was a Madison Ave. kinky from the 60s I spent a season after leaving Alfred University getting to know the ins and outs of the ad.business from a mentor from B.Altman. As an “old woman” I still enjoy a clever advertisement. A very good job!
