I saw a commercial for this on the teevee last night and had to share.
KMBC & KCWE are saying "Thank You" to loyal viewers on Wednesday, June 13th with Free Sheridan's Custard. You can get a regular chocolate or vanilla custard with two toppings for free from 11am to 11pm.
Here's a link to the TheKansasCityChannel.com with more details including participating locations.
Don't eat all the custard, I beg you.
