Sandwhich...making-taste-bad ideas?

[Doodle]

So at lunch, there's this person who likes my sandwhiches. I don't. So I give it to him. But I feel like surprising him with a not so good  sandwhich. >:)

So, what are some ideas? It shouldn't really be something noticeable, because he checks. :P

Um, put ketchup/jelly/some condiment under a big piece of meat.

Well, stick with jelly. Something disgusting that no one likes.

Make it a normal sandwhich, and have one of your friends shout something that'll make him turn around. Switch the sandwhich with a sandwhich that has either a)Jelly underneath ketchup, blue cheese and marshmallow (Or a combination of those), or b)A sandwhich with a roach in it. Watch him/her squeal with fright!

Shit on a piece of bread and slap another piece on top of it.

And you're done.

Take the meat, and slide it between your butt cheeks.

I believe Kaz outdid you, there.

Oh, another idea. If you haven't clipped your toe/finger nails in a long time, now's the time to do it :P

[Silverhawk79]

Squeeze some lemon juice all over the meat/cheese, along with maybe some expired meat/cheese.

[Tupin]

Use rotten meat and put dog poop in it.
