hilarious, joyous regret

Upon discovery that she had been running her entire life with exercise-induced asthma, Dominique felt a wave of regretsenstrudel wash over her like cloyingly sweet, suffocating relief.

regretel 

What an animal wif a securely-gripping prehansel tail never feels when hanging from a branch.

Maybe if da two famous fairy-tale children had possessed preHANSEL tails, they might have been able to traverse da forest by swinging through da tree-tops, and thus they could have avoided feeling da reGRETELs of getting caught by da wicked candy-cottage witch, since she could not have reached them when they were up dat high.
