The next day she comes in a ginger wig and says
'can i buy that tv?' he says again 'we don't sell to blondes'

Then she came in the next day with a brunette wig and said 'can i buy that tv?' and the shopkeper says
'we dont sell to blondes'

then she asks how did you know i was the same person as before? and the shop keeper says because its a micro-wave not a tv.

looool
