a colleague has fucked you off and it's your turn to make tea....

A bit of finely ground-up glass should put the shits up 'em (probably quite literally).

 

[Chorlton]

tell them you are going to make a cup of tea, let them sit there and mentally prepare for it, looking forward to their lovely cup of tea, but really emmigrate to canada, start a family, and become interested in NHL - that'll show them

I'm a big fan of the "volcano brew"
Put the milk in first, microwave it till it's boiling.
Put boiling water in & make the 'brew' in question.
Re-microwave till it's bubbling & boiling again.
Carefully place (using oven gloves/teatowel) in 'their spot'.
It will remain too hot to touch for ages, hopefully they'll just grab it, scream & throw it everywhere

Stink palm a la Mallrats.

Pop to the loo first and wipe your hand and palm firmly up and down yer bum crack. Then go and get the receptacle of choice and rub your stink palm all over it paying careful attention to the rim. Then proceed with tea making. To make it more convincing as a lone brew up you could conveniently forgot to make one for them and then go back and do a 'special' cuppa just for them.

A really good thing to do is pretend that the cup is really full but actually its empty. Carry it towards them like you being really careful not to spill it.

Then just when you get near them just launch the cotents into their face and watch them try to dive out of the way. Then laugh harder than you have ever laughed in your life...right in their face.

It might get you sacked for being a nutter but oh the satisfaction.

Word !!

Or ya could just tie em up and tea bag em?

 

[Space Girl]

a drop or two of optrex in their drink, wait a few hours then watch them run to the loo, if you do this a 3pm, come home time on the bus/train etc they will be in real shit, literally

I'm interested that Winkybag's suggestion alarms you, but my ground-up glass proposal does not

 

[pinched_nerve]

Put in Jif/Cif instead of milk, that'll learn 'em.

Other than that, too much or too little sugar

I'd lean towards the latter.
