'''Yay Ka-Boom-Boom''' is a mission in [[Grand Theft Auto: San Andreas]], given to [[protagonist]] [[Carl Johnson]] by [[San Fierro Triads]] leader [[Wu Zi Mu]] from the [[Doherty Garage|garage]] at [[Doherty]], [[San Fierro]], [[State of San Andreas|San Andreas]].
The [[Loco Syndicate]] is now finished, and the only thing left to do is to destroy the yay factory in Doherty. Wu Zi Mu's guy has set a wired car for the job. Carl then goes to the garage in [[Downtown San Fierro|Downtown]]. CJ picks up the car and goes to the factory. The gate is closed and there are two guards. Carl kills the guards and the gate is opened. Here, more men inside try to kill CJ, who eventually kills them all. CJ gets inside the factory and parks near the chemical containers. He activates the bomb and he has to run away. He gets out of the building, and a [[Voodoo|car]] gets in the factory. Carl kills the people carried by the vehicle, and gets out of the factory via a ramp, since the gate was closed. Carl safely gets back to his garage, ending his syndicate worries in San Fierro.
'''Cesar Vialpando''': Carl! You're a fucking hero down in [[Los Santos|LS]], I just spoke to my cousin.
'''Carl Johnson''': Not wit' my people I ain't. Shit's still fucked up. Man, I got homies I used to run with that turn their back on me, over this.
'''Cesar Vialpando''': Yeah, well, what are you going to do, huh?
'''Carl Johnson'''; Fucking Ryder man! That was my homie! And I've killed him!
'''Cesar Vialpando''': Fucking midget deserved it, eh. Little asshole tried to bang your sister, you know that?
'''Carl Johnson''': ...No...For real...? Shit. Maybe you're right, then, man. But...
'''Cesar Vialpando''': Cheer the fuck up! You're going soft on me, man. You did something good, eh?
'''Wu Zi Mu''': Yes you did. But this isn't over yet.
'''Carl Johnson''': What you mean?
'''Wu Zi Mu''': Well, your former friends have a factory. And the way I see it, if you take that out, you will have put them out of business for good.
(''Outside the garage, phone ringing, Carl answers'')
'''Carl Johnson''': Yeah?
'''Carl Johnson''': Who is this?
'''Guy''': I work for Woozie he told me to call you.
'''Carl Johnson''': Alright, wassup?
'''Guy''': I'm rigging a car with explosives so you can take out the crack factory! Drop 'round the garage Downtown.
'''Carl Johnson''': Cool. I'll be at you in a minute.
(''Carl arrives at the garage in Downtown'')
'''Carl Johnson''': Hey man, is it ready?
'''Guy''': She's all set. Get in. She's packing enough to take out that crack lab. I've wired in a delay timer, to give you time to get out.
'''Carl Johnson''': Cool. Good lookin'.
(''Carl, arriving at the factory'')
'''Factory worker''': We're being hit! Open the gates and waste the dumb fuck, holmes!

The rewards for this mission are [[Money|$]]25,000 and increased [[Respect|respect]]. The missions [[Monster (mission)|Monster]] and [[Zeroing In]] are unlocked, with the latter mission needing the [[Driving School]] be passed first. The player may also now traverse [[Tierra Robada]], [[Bone County]] and [[Las Venturas]] without getting any [[San Andreas Police Department|police]] attention.
*The wired car has a special numberplate 'TIME8OMB'
*The mechanic's actor, who supplies CJ with the rigged car, also voices many other characters in the game including Wu Zi Mu's assistant. Fans found this to be very repetitive, however it isn't a big issue.
*In previous games,when you drive a car that has a bomb, a damage bar appears, which if filled up, makes the vehicle explode. In this mission, you drive a rigged car, but there's no damage bar.
*Jumping from the ramp will give you a [[Unique Stunt Jumps|unique stunt jump]] bonus. If the jump wasn't successful, try again after the mission. The gate will be opened.
*There is a subtitle error in the post mission phone call; CJ says' Speak on it', however the subtitle's read 'Yes?'
