Dan versus nature

"Shy and scrawny Dan Weekes spends his time creating graphic novels inspired by his dream girl and looking out for his mom as she dates every man in the state of California. Then his mom drops a bomb: she and her latest beau, Hank, are engaged, and she's sending her 'two favorite men' on a survivalist camping trip to 'bond.' Determined to trick Hank into showing his true colors on the trip, Dan and his nerdy germaphobe best friend, Charlie, prepare a series of increasingly gross and embarrassing pranks. But the boys hadn't counted on a hot girl joining their trip or on getting separated from their wilderness guide--not to mention the humiliating injuries Dan suffers in the course of terrorizing his stepdad-to-be"--Amazon.
