What would have been funnier and a bit more Indiana Jones-ish was if he hid, the bomb hit the ground and no explosion. But, Indy has now locked himself in the refrigerator and a bunch of sheepish Army guys have to get him out. A mile away from the site, on their way to take Indy to jail (Jones recently free from the fridge), the bomb suddenly and unexpectedly explodes. The car gets thrown, Indy survives the car crash but he and the Army guys get doused with radiation. While he is in the shower getting scrubed down, Indy turns to one of the cleaners and grumpily says, "You should have left me in the refridgerator."
