Why?!

in the previous post i mentioned:

hunghui: what animal says why?

someone: i dunno

hunghui: a dog

someone: why?

so let me continue the story, hunghui pls dont kill me! :D

(cause our ex chem teacher told us asking why (asking questions) is good and ervin started asking why to annoy him.)so when hunghui told me the joke,

i went: huh so ervin's a dog lah? (no offence to him)

hunghui: why?

everyone there: -burst out laughing-
