Ha!
Yeh, one can't properly give another a cliff-notes version of the Elder gods & expect "oh wow, sounds great." For those that haven't read Lovecraft but love the Evil Dead movie trilogy, the Necronomicon was based on Lovecraft's works.
As for relaxing good laugh reads done well, I'd have to strenuously recommend Christopher Moore. One of the few that can wonderfully blend slapstick w/ wit, much like Monty Python or Douglas Adams. All his tomes are a great time, but esp:
"Lamb. The Gospel According to Biff, Christ's Childhood Pal." hilarious & surprisingly touching in parts
"Fool." - effectively the story of Lear{w/ a mix of other Shakespearean references} as told by a jester called Pocket. One of my all-time favorite humour tomes.
If you really like Shakespeare & the absurd, Robert Nye has a cpl Shakespeare inspired books. Really really bawdy & lecherous. "Falstaff" is my favorite.
His treatment of "Faust" is excellent as well.
Happy reading!
