Wallace Langham plays the character Phil on the Larry Sanders show on HBO. He is pictured here from an episode where, as you can see, he is wearing a Cows t-shirt:

I had mentioned before how I was going to try to find out if it was Wallace's shirt or if it came from the wardrobe department or what, and I guess Wallace found out somehow about the Cows page, because he signed up for the mailing list with the following comments:

Yes, it was my T-shirt, purchased some years ago at Urban Outfitters strictly for the design. Now, I could be a complete poseur and claim that COWS are my favorite band, but, I have not actually heard them. Will remedy that soon at the local Virgin Mega-store. We are starting a new season of The Larry Sanders Show in Oct., where I will wear my COWS shirt proudly. If for some reason this is an affront to COWS, please let me know. Then I will be happy to burn the shirt on-air in effigy (maybe too harsh, huh?) Keep me posted as to future COWS goings on. Your newest fan, Wallace...
