Q: Is there a ceremony for converting from republican to democrat?
A: Yes, a politician who wishes to convert from republican to democrat must undergo a circumcision to remove the foreskin from his heart.
The ceremony is accompanied by the recitation of various appropriate biblical verses such as:
Deuteronomy 10:16 - Circumcise therefore the foreskin of your heart, and be no more stiff necked.
Deuteronomy 30:6 - And the Lord thy God will circumcise thine heart, and the heart of thy seed, to love the Lord thy God with all thine heart, and with all thy soul, that thou mayest live.
Jeremiah 4:4 - Circumcise yourselves to the Lord, and take away the foreskins of your heart, ye men of Judah and inhabitants of Jerusalem.
