Please explain this pun, "well, then is my pump well flowered." ll. iv. 62Romeo and Juliet by William Shakespeare

There are other translations of this pun in Act II, scene
4 of Romeo and Juliet.  A pump is a
light shoe.  This definition is given in the Modern Text
of Romeo and Juliet noted as such in an edition by John A Price.  In this
line,Romeo makes a pun on another use for "pink" which Mercutio uses in "I am the very
pink of courtesy," with "pink" meaning Mercutio is a paragon of courtesy.  Romeo plays
on the word, saying "pink for pattern." In Romeo's line, "Pink"means to decorate in a
perforated pattern."

Then, Mercutio says to keep jesting
until the sole is worn out, punning on the words sole/soul; Romeo finishes the pun by
saying,

O
single-soled jest, solely singular for the singularness! (II,iv,64)  [the pun is
singular/unusual because of its silly
simplicity]
