Do you reckon that suicide bombers ever call in sick?

1. a = b
2. a – b – 2 = a – b – 2
3. a(a – b – 2) = b(a – b – 2)
4. aa – ab – 2a = ab – bb – 2b
5. aa – ab = ab – bb – 2b + 2a
6. aa – ab = ab + 2a – bb – 2b
7. a(a – b) = a(b + 2) – b(b + 2)
8. a(a – b) = (a – b)(b + 2)
9. a = b + 2
10. b = b + 2
11. Therefore, 0 = 2
    

1. a = b + 1
2. (a-b)a = (a-b)(b+1)
3. aa – ab = ab + a – bb – b
4. aa – ab -a = ab + a -a – bb – b
5. a(a – b – 1) = b(a – b – 1)
6. a = b
7. b + 1 = b
8. Therefore, 1 = 0
