My identical cousin Thimbles O'Hooligan writes on Facebook:
I've had a brainwave that'll help that nice Mr Trump build his wall. Taxpayers don't want to pay for it, Mexicans won't pay for it. Trump supporters want it, so why doesn't he start a fund, put in, say, $5 million of his own money to build the first mile, get his billionaire friends to sponsor a mile each. his poorer supporters could club together and pay for a few feet, get their names on it. Then see how far it gets. When we contributed to a theatre project some years ago we could have our name on a brick, larger donations got you a named seat and so on right up to naming an auditorium. Surely his supporters would rush...
