Oh Boy I can think of numerous times where I have laughed while watching this anime..first when Ichigo-chan told Masha to do her summer homework and he drew something on the paper instead,then Pudding,Retasu and Minto-chan's reaction to the cat who Ichigo-chan said could talk but he didn't (to them anyway),then when Pudding-chan asked for a tip at the end of Episode seven and when Ichigo-chan said she would sue Ryou in the preview of episode 28 and when Ryou said to sue him if she turned into a cat again in episode 28!..and there were many other times as well those are just the ones that come to mind now!

Yeah i have so many times but i cant remember
wich ones O.o

Lots of times! 1) Ichigo is slapped by minto on the hand for being "vulgar." 2) Ichigo is stalked by pudding all day for cat ears. 3) runtruntruntruntruntruntruntruntruntruntru­ntr­unt­run­tru­ntr­unt­run­t. 3) Minto is the only one with table manners! 4)Everybody is saying something like, "how dare you interrupt lettuce when she was going to confess her love!" Zakuro is silent. Apparently she doesn't care about lettuce. 5) Ryou: 2000 yen a subject, please. 6) The girls get all scared because they think bachigappa is trying to kill them.
And many, many more.
