Soap & Water
One day a man asked a friend to come over to his house for dinner. He agreed and upon arriving, sat down to eat. He noticed the plates looked a little "hazy" and he asked "are these plates clean". The host replied assured him that "all my plates are as clean as Soap & Water could get them.
This relaxed the guest who enjoyed a delicious dinner. After the meal as the two friends sat down to enjoy an after-dinner cigar, the guest noticed the hosts two dogs outside and commented how good they looked and could the host let them in so he could meet them. The host responded "of course, they have their own dog door... I'll call them in. The guest was reflecting on how tasty the meal had been when his host called out... "Soap.... Water, come here boys!!
