Limerick Number 328!

If A equals B (so I say),And we multiply both sides by A,Then we'll see that A squared,When with AB compared,Are the same. Remove B squared. Okay?Both sides we will factorize. See?Now each side contains A minus B.We'll divide through by AMinus B, and ole!A plus B equals B. Oh whoopee!But since I said A equals B,B plus B equals B, you'll agree?So if B equals one,Then this sum I have done,Proves that two equals one. Q.E.D.
