Carpe,
The Sponge Bog commercials started before the weekend. I was washing my truck with the sponge last night (first time) with my 11 and 5 year old boy's. The older boy asked if I needed my bucket and soap and I said no, the soap is already in the sponge. My little guy responds "hey daddy just like the Sponge Bob sponge." I asked how he knew about the Sponge Bob sponge and he said he saw it watching Sponge Bob when he was at daycare (which was last Wednesday 8/5). So you have confirmation from my 5 year old that the commercial has been out for a full week now.

PS The sponge worked great on my truck, but the chamois didn't work so well.
