ehe good one, 

here are some baap/beta jokes from me: 

1)Beta: Abha meine shaadi karni hai 
Baap: Acha! yeh to bohat khushi ki bhaat hai, batao to sahi, woh kush naseeb larki kaun hai? 
Beta: Woh ladki meri daadi hai.. 
Baap: no beta, aap unse shaadi nahin kar sakte, woh to meri maa hain... 
Beta: to phir aapne meri maa se shaadi kyun ki? 

2)Baap: pados ki ladki ko dekh, woh exam mein first aayi hai. 
Beta: usko hi to dekh ta rehta tha, tabhi to fail ho gaya.. 

3) Baap: Beta is bar exam main tujhe 90% lene hai, kuch bhi kar.. 
Beta: Nahi Baapu, main to is bar 100% lunga...! 
Baap: Kyon Mazhaak kar raha hai..? 
Beta: Shuru kisne kiya..?!! 

4) a guy goes to the store with is father: 
Beta: Abha, kiya mein yeh baaja le sakta hoon? 
Baap: no, beta, mujhe daar hai ke tum mohale waalon (neighbours) ko tang karoge, jab woh din mein kaam kar rahe honge... 
Beta: nahin, abha, mein aapse waada karta hoon, mein baaja tab bajaoonga, jab sare mahale waale sau (sleeping) rahe honge.:)
