"Anagrams" joke

An anagram is, if you don't know, a word or phrase made by transposing or
rearranging the letters of another word or phrase. The following are
exceptionally clever!
Dormitory = Dirty room
Evangelist = Evil's agent
Desperation = A rope ends it
The Morse Code = Here come dots
Slot machines = Cash lost in 'em
Animosity = is no amity
Mother-in-law = Woman Hitler
Snooze alarms = Alas! No more Z's
Alec Guinness = Genuine class
Semolina = is no meal
The Public Art Galleries = Large picture halls, I bet
A decimal point = I'm a dot in place
The earthquakes = That queer shake
Eleven plus two = Twelve plus one
Contradiction = Accord not in it
Princess Diana = Ascend in Paris
This one's truly amazing:
"To be or not to be: that is the question, whether tis nobler in the mind to
suffer the slings and arrows of outrageous fortune."
And the anagram:
"In one of the Bard's best-thought-of tragedies, our insistent hero, Hamlet,
queries on two fronts about how life turns rotten."
And for the grande finale:
"That's one small step for man, one giant leap for mankind".
The anagram:
"Thin man ran, makes a large stride, left planet, pins flag on moon. On to Mars!"
