A pun to share

[majiskdqvp]

 
Three rats are sitting at the shut out talking bragging here their indomitability and toughness.
 
The first says, "I'm so hard, decidedly I ate a chiefly bagful of rat blight!"
 
The second says, "Fabulously I'm so leathery, from time to time I was caught in a rat ruse and I bit it apart!"
 
Then the third rat gets up and says, "Later guys, I'm off poorhouse to harass the cat."
