"Are you sure we can pull this off?" Rodney peeked around the corner nervously.
"It'll work," Sheppard answered and tightened his hold on the string.
Carson stared at them curiously. Rodney kept peeking around the corner while Major Sheppard held a bucket up with a string. Carson wondered briefly what was in it. "What are you two up to?" he asked, watching as Rodney jumped guiltily and Sheppard looked startled enough to almost drop the string.
"Carson! You weren't supposed to come through that hall-" Rodney yelped as Sheppard clamped a hand over the scientist's mouth.
Carson hid a grin. "Is this the payback for the Easter costumes?" He studied the bucket. "What's in it?"
Sheppard sighed and took his hand off Rodney's mouth. "Guess the jig is up. Whatever we could get our hands on."
Carson stood on tiptoes and peeked into the bucket. "Seems a shame to waste it," he observed, then leaned in conspiratorially. "I think that Kavanagh man's coming by here."
Sheppard shrugged. "Can't hurt. Rodney, what do you think?"
Carson peeked around the corner. "Better do it now- he's almost there." He turned back.
Rodney snatched the string from Sheppard quickly and muttered about 'undermining my authority' and 'like to see him try that again'.
There was a yelp of disgust as the bucket tipped over, spilling its contents on Kavanagh.
Carson turned to walk away. "I should be getting back to the infirmary now." He sprinted down the hall as Kavanagh squelched his way around the corner.
Rodney and Sheppard hid their laughter in their hands as they looked at their handywork stuck to the back of Carson's coat, reading in large block letters 'Hug me, I'm Scottish'.
"Yes," Sheppard grinned smugly, "In life and April Fools, it's always good to have a Plan B."
