Cartoon-Style Book Cover for Male Romantic Comedy

I am just completing first full length novel and will be self-publishing. I want a suitable eye catching funny cover that will work both on paperback and E-book.

The book is currently called 'First Years' about a house full of first year male students. It needs to appeal to men and women and show the book is funny. The adventures in the book include sexy undies, raiding fish ponds, nine legged pub crawls, difficult Maths tests and teaching practice, and a scary German Cleaner. Oh and it is set in 1986.

So any similar experience anybody can show me would be great.
