I doubt that I ever had a favorite commercial, but perhaps Aflac (quack), is cute. Gilbert Gottfried gets my attention. Now to do Kermit I read.
I also like the geico commercials but can't stand Gilbert Gottfried...so irritating and annoying. Did read that Kermit's voice was going to be done by someone else but didn't know who...glad my grandsons are past that stage. Actually it was my kids that were more into Sesame Street and the muppets than my grandsons.
Unique voices sometimes grit on the nerves like finger nails on a black board. I don't mind Gottfried but there are a couple in R.L that make me shiver. Gilbert I can turn off. Some that bothered me. Still. Willie Nelson Fran Drescher BullWinkle Margret Hamilton.
