He then has dirt thrown at him while he's driving, but the man gets away.
Then a van speeds by with inside a female volley ball team that are undressing themselves, as the girls are changing in their van, one girl accidentally drops a piece of clothing, Jon and Ponch give chase.

As they catch up with the van, Ponch tells the girls that he only wants to speak to the driver, with this the girls all climb out of the van; naked. Jon and Ponch focus on each other so as not to look at the girls. Then Ponch issues the driver with a speeding ticket.

At Central Getraer puts everyone on a diet. 1000 pounds is to be lost by the CHP.

Cruising the highways a nervous learner driver gets mud thrown at him from that guy who did the same to Ponch earlier and looses control -> crashing.

Back at Central at the last physical Grossie was 209 pounds, Grossie claims that it is his natural body weight and gets out the family album to show he was a chubby child, unimpressed Getraer announces that Grossie must loose 18 pounds, and Jon and Ponch 5 pounds each.

Later that night Jon and Ponch stake out the dirt thrower, after a brief chat with him he runs off.

In the early morning Jon, Ponch, Grossie and Getraer are jogging, but Jon and Ponch stop to play volley ball with the girls (fully clothed) they met they other day

Later in the day Jon and Ponch find the dirt thrower and arrest him.

Back on the freeway an explosive truck is driving along and is going to blow up, Jon risks his life to drive the truck to a disused space on the freeway to allow it to blow up without danger to others, he tells Ponch to stay with the traffic, but Ponch having none of that drives of on his bike after Jon to save him, as Jon jumps out of the truck onto Ponch's bike, Ponch quickly drives away, but as the truck explodes they are both blown of the bike, on the grass Jon tells Ponch he broke procedure, Ponch says:"so report me". They smile at each other.

In the end the CHP loose their 1000 pound target, and Grossie looses 8 pounds.

Then Jon and Ponch ask Getraer to get back on the scales, as he does so, Grossie has added another weight, as the music plays out a baffled Getraer cannot understand how he had gained 10 pounds, poor sarge is all confused.
