Failed Joke 2

Due to problems with my laptop it is possible that I won't be able to continue updating my blog daily. But hopefully I will, I just thought I'd better write something now so that it's clear in the future that that is the case, if there's no new entry.
    Anyway, I'm sure you can remember my entry entitled Failed Joke, well this is basically another instance of me trying, and failing, to be hilarious:

Friend: Hey, I'll be right back, just going to the toilet...
Me: Okay then.
(a few seconds pass)
Me (thinking): Hmm, wait a minute; they didn't lock their laptop... I can do what I want with it! I think I’ll play a very funny prank heh heh... *goes onto Google searches for pictures of radishes*
*Friend comes back in*

Planned reaction:
Friend: Wait a second... I don't remember searching for radishes on Google Images...
Me: That's because it was me!
Friend: Hahahaha! That's so funny, it's even better than your gullible joke that you played on me before. This really has solidified our friendship!
Me: :)

Actual reaction:
Friend: Wait a second... What have you done...
Me: Oh nothing... :D
Friend: Why did you search for radishes?
Me: I didn't, it's on your computer, you must have done it...
Friend: Except you did it while I was out of the room.
Me: ...
Friend: You're so weird.
Me: :(
